Features

• #7439: It is now possible to restore an auto saved editor instance, when starting a new editor on the client. This is possible by using the REST API and the restoreAutosave option. With the REST API it is possible to move an auto save state from one server to the other, the restoreAutosave option allows to restore from the auto save state with a given document and user ID.
• #7360: It is now possible to define a document (defaultDocumentTemplate(Url)), which should be loaded by default when starting the editor or invoking the new-document action.
• #7331: Words can now be stored persistently on the server if the applicationDictionaryDir server parameter is configured.

Improvements

• #7460: The promise returned by calling invokeAction on a custom JavaScript action can now be resolved within the invokeListener of the custom action. See the example below:

  var testAction = editor.getAction("test-action");
  if (testAction !== null) {
      testAction.addInvokeListener(function(e) {
          
          var p1 = editor.fetchBodyFragment();
          var p2 = editor.fetchNumberOfCharacters();
          
          jQuery.when(p1,p2).then(function(valp1, valp2) {
              
              var str = "<html>"+valp1 + "<p>Original document contained "+valp2+ " characters</p></html>";
              editor.loadDocument(str).then(function(ld){
                  e.deferred.resolve("Ready");
              });
          });
          e.preventDefault();
      });
  }
                      

  Please note that it is necessary to call e.preventDefault() so that the promise e.deferred is available.
• #7135: Improved error handling/logging when trying to use a comparison API method without a comparison license.

• The "Administrative GET requests" were removed and replaced by an official REST management API (see REST tutorial). The Nimbudocs Editor Management REST service runs on a different port and (base) URL: http://yournimbudocsserver:9424/management/. Without an installed Management Service, the Webmin administration interface will not function correctly.
• Removed server parameters: customFontContextPath, fontCacheContextPath and imageCacheContextPath. All those resources are now delivered by the Nimbudocs Editor REST API. It is still required to configure the customFontFilePath if you want to use custom fonts.

Release 2.4.4130 (released 2018-11-22)

Bug Fixes

• #7493: Resolved issue with restoring the editor from (disc) hibernation.
• Resolved memory issue when consecutively hibernating(disc)/restoring the editor.

Release 2.4.4099 (released 2018-10-12)

Bug Fixes

• #7366: Refined resolution of issues which could occur when waking up the editor from hibernation through API calls.
• #7438: IE 11: Dropdowns in a dialog are usable again when having a selection in a table.

Changes

• The hibernateEditor method now returns a promise that will be resolved as soon as the server is hibernated.The promise will be rejected when calling hibernateEditor() while the editor is already hibernated or the editor is restoring from hibernation. It is not required to use the promise, as API calls invoked directly after "hibernateEditor()" (programmatically or by user interaction), will be queued to execute after hibernation has completed. Nevertheless it is recommended and good practice to use the promise, as instantly calling an API method will lead to the situation that the editor is restored as soon as the promise is resolved due to the queued API call.

Release 2.4.4086 (released 2018-09-13)

Features

• #7205: Added API method to explicitly hibernate the editor (optional remove also from memory as soon as possible).

• #7366: Resolved issues which could occur when waking up the editor from hibernation through API calls.

Release 2.4.3933 (released 2018-03-14)

Bug Fixes

• #7213: Fixed an issue where placing the caret and typing in a read-only section caused the caret to move to the left and insert content once it reached an editable element.

Improvements

• #7214: It can now be configured via CSS if typing between read-only elements is allowed. Two new CSS properties were implemented for this purpose: -ro-prevent-insertions-before and -ro-prevent-insertions-after. Please see the CSS Property Documentation for details.

Release 2.4.3926 (released 2018-01-06)

Bug Fixes

• #7118: Additional improvements for "Typing over fully or partially selected content with an inline format no longer removes this inline format".
• #7137: The Auto Correct dialog can now be closed correctly.

• #6997: Added metrically compatible fonts for Arial, Times New Roman and Courier New to the font drop down in Nimbudocs Editor. Those fonts were already included as base/core fonts and originate from the "Croscore fonts collection", which is also the base for the "Liberation" font package. The fonts added are the following:
  • Arimo (corresponds to Arial and Liberation Sans)
  • Tinos (corresponds to Times New Roman and Liberation Serif)
  • Cousine (corresponds to Courier New and Liberation Mono)

Bug Fixes

• #6957: Editor can now be hibernated/removed correctly if there is an exception while retrieving caret information.

Changes

• IMPORTANT: The Virtual Appliance is now based on CentOS 7.

• #6245: It is now possible to have only one row of icons in the tool bar
• #6328: Added two ways to show messages in the editor:
  • showInfoBox() API method, to display a modal dialog with information.
  • showStatusMessage() API method, to display information in the status widget (non-modal, unobtrusive).
• #6415: Added new setDocumentName() method that sets an identifying name for the next document that is loaded. The name will then be displayed in the server log when the document is loaded.
• #6438: If the connection is lost, the client now tries to reconnect to the server automatically (10 retries in an interval of 5 seconds).
• #6478: Added an option to enable the spell checker by default.
• #6570: The title of the header/footer editor dialog is now context dependent (Header or Footer, specific page).
• The overlay and loading indicator is now configurable using the overlayAndIndicator configuration option (color, opacity, alwaysTransparent, alwaysHideIndicator).

Improvements

• #6435: The reconnect button is now clickable even if the overlay is displayed.
• #6439: Added a new state still-disconnected to the onconnectionstatechange callback. The callback will now also be called when reconnecting fails.
• #6497: The caret is now disabled and typing is prohibited in comparison mode. Also the "prohibited" symbol (read-only) is no longer visible in comparison mode.
• #6526: Added support for the CSS property transform-origin.
• #6573: The "longpoll aborted" state is handled more gracefully.
• #6596: Improved error handling/logging when empty/undefined/null arguments (of API methods or actions) are sent to the server.
• Improved typing on mobile devices.
• It is now possible to type using an IME.
• It is now possible (again) to remove a registered EventListener.
• Empty bookmarks are now visualized using a small icon (this also resolves #6104).
• Updates from the server are now more fine-grained. This reduces the amount of data that is sent from the server and improves performance.
• Context (sub) menus, which contain a lot of entries are now "scrollable".
• Added new Inline-Editing sample.

Bug Fixes

• #6434: The Tinos font can now be used correctly.
• #6436: It is now possible to use the -ro-source-page CSS property for background PDF images.
• #6493: The lang and xml:lang attributes are no longer removed when using one of the importLegacy methods.
• #6494: It is now possible to set a document language when the document has no initial lang attribute.
• #6539: The selection is no longer lost when changing table attributes with the "setElementListAttributes" method.
• #6574: Copied editor content from Internet Explorer is no longer surrounded by line breaks.
• #6580: Fixed issue when closing the header/footer editor dialog before the editor was fully loaded.
• #6611: Fixed issue with pasting plain text in Windows Chrome / Firefox
• #6618: Fixed issue with list context inside td elements.
• #6632: The apiKey set in the editor's config object is now also passed through to the header/footer editor.
• #6634: It is now possible again to edit the right page footer.
• #6639: Editor no longer causes high CPU load due to endless iterations under specific circumstances.
• #6641: Tooltips no longer are permanently displayed in certain situations.

Changes

• All existing style sheet manipulation methods in Nimbudocs Editor have been deprecated. We now have the following new methods:
  • addDocumentStyleSheet, clearDocumentStyleSheet, removeDocumentStyleSheet, fetchDocumentStyleSheet (replacing the embedded style sheet methods)
  • addAuthorStyleSheet, clearAuthorStyleSheet, removeAuthorStyleSheet, fetchAuthorStyleSheet (replacing the user style sheet methods)
  • addEditorStyleSheet, clearEditorStyleSheet, removeEditorStyleSheet, fetchEditorStyleSheet (replacing the user agent style sheet methods)
• Changes to the editor session management/cleanup:
  • Editor sessions will now be hibernated in memory after 3 minutes. In this state they require less memory, however they still count towards the editor session limit.
  • The hibernated session will be cleaned from memory after 10 more minutes and thus no longer count towards the editor session limit.
  • Additionally an editor session will be auto-saved to the file system of the server every 10 seconds (if there are changes) as long as the session is active.
  • Resuming an editor is possible from the memory hibernation mode and from the auto-save state in the file system (even after a server restart) as long as the user does not close the client side session (browser tab). Resuming is transparent for the user, as clicking in the editor suffices to resume/restore the editor.
  • Restoring an editor from disc is only possible if the session limit is not yet reached. If there are no free sessions, restoring behaves identical to opening a new session - the onsessionlimitreached callback will be called and by default a dialog with a retry button will be displayed.
  • If the connection is "lost" because the editor session was removed on the server (and is only available as auto-save file) a different icon is displayed and the "onconnectionchange" callback receives the status "editor-session-server-removed".
• Changes to server side configuration:
  • Removed editor-session-timeout
  • Added: autoSaveInterval, autoSaveTempDir, hibernateCleanupTimeout, hibernateCleanupTimeoutCheckInterval, sessionHibernateTimeout, sessionHibernateTimeoutCheckInterval, storageCleanupCheckInterval, storageCleanupRetentionPeriod
  • Unified notation: Parameters are now all camel case (customfontfilepath -> customFontFilePath).
  • Server configuration should no longer be made in the nimbueditor.xml (/ro/jetty9/webapps) context file, but in the nimbudocseditorserver.config configuration file in /ro/nimbudocs/config. See also the Server Configuration guide. If you have a nimbueditor.xml.rpmnew after the update, please make sure to transfer the configuration settings from your modified nimbueditor.xml to the new configuration file and replace your old nimbueditor.xml file with the .rpmnew file afterwards.
  • Changed the way the license key has to be installed: The licensekey.txt has to be uploaded via webmin or put into the /ro/nimbudocs/config directory. Alternatively now you can also configure the license key location by specifying the licenseKeyPath configuration parameter in the nimbudocseditorserver.config file.
• When no license key is set the server now runs in an evaluation mode which allows 3 concurrent sessions and displays evaluation notices in the editor.
• Changed the default theme. The previous theme can be enabled by setting the theme option name property to nimbudocs-classic.
• Updated Java to 1.8.0_112
• Updated Jetty to 9.3.14

Release 2.3.3451 (released 2016-06-22)

New Features

• #6340: Added a reconnect method in the "onconnectionstatechange" callback (when the connected state is false).
• #6374: It is now possible to change the server side log level (from the Webmin interface) without the need to restart the application server.
• #6398: Added an "oncontentchange" callback which is triggered when the content of a document or the document itself changes. This is a replacement for the (deprecated) "hasContentChanged" API method.

Improvements

• Improved the way requests are sent to the server. Commands will now be queued on the client if there is already an active request. Queued commands will then be sent as bundle as soon as the previous request returns. This improves the overall connection reliability.
• Clicking in the side bar no longer removes the focus from the editing area.
• Dialogs in the side bar (collaboration related) will now be closed automatically if clicking somewhere else in the editor.
• Improved server side (error) logging.

Bug Fixes

• #6192: Table cells are now correctly displayed after adding a column.
• #6293: Adding and removing table columns/rows now works properly in nested tables.
• #6311: Justify is now correctly applied if there is a floated element beside the justified content.
• #6314: Preventing exception when loading document with a root element that is not "html" (e.g. XML documents).
• #6318: Resizing an image or shape in continuous mode (e.g. header/footer dialog) now works correctly.
• #6335: (Web)Fonts specified via @import are now loaded in Nimbudocs Editor.
• #6341: It is now prevented that the longpoll is hibernated/woken up if the server is disconnected.
• #6385: Fixed issue in internal layout process which could lead to "infinite" recursions and StackOverflow errors.
• #6407: Pressing enter in the search dialog in IE 10 no longer opens the "About" dialog.
• Fixed an issue which could cause incorrect initialized editor sessions ("null" sessions).

Changes

• Changed clean-up behavior: Non-closed inline elements are no longer repeated until the end of the document, as this could lead to a lot of nested/duplicate elements.
• Added additional clean up when loading a document: Identical nested inline elements (abbr, acronym, b, bdo, big, blink, cite, code, del, dfn, em, i, ins, kbd, q, ruby, rbc, rtc, rb, rt, rp, s, samp, small, strike, strong, sub, sup, tt, u) will be collapsed. This should resolve issues with nested/duplicate elements in documents which were cleaned with the "old" clean-up settings.
• Deprecated the "hasContentChanged" API method. Use the "oncontentchange" callback instead.
• Disabled the "Hot Deployment" mechanism of the Jetty application server. Changes to the nimbueditor.xml (or other context files in the webapps/ folder) no longer trigger an application server restart.
• The "Undo/Redo" stack is now limited to 50 steps by default. The value can be configured in the nimbueditor.xml (undoLimit).
• Changed behavior of the +/- Table handle buttons: They will now always insert a row/column after the last row/column or remove the last row/column.
• Removed the default style templates for H1-H6. They are now included in some of the samples. To ensure backward compatibility the action IDs previously provided by the style templates are now implemented as normal actions.
• Jetty was updated to version 9.3.9.
• Java was updated to version 1.8.0_92.

Release 2.3.3439 (released 2016-04-22)

Bug Fixes

• #6287: Video elements are now displayed correctly again.
• #6288: Fixed an issue with the importLegacyDocument* methods.
• #6291: Fixed an issue with toggling/updating custom style template actions in the tool bar.

Changes

• Changed Copy and Cut behavior:
  • When something is selected in the editor, the server will always send the selected content to the client (asynchronously, in the background).
  • The copy action is disabled until the content was received by the client
  • The dialog introduced with 2.3.3423 will now only be displayed if the selection is larger than 1MB (The value is configurable with the new "clipboard" configuration option).

Release 2.3.3423 (released 2016-04-12)

New Features

• The default tool bar icons are now loaded as "sprite" icons (all icons are combined into a single image, a single icon is accessed through CSS background position) to minimize HTTP requests on startup of the editor. You can still use custom icons as before (i.e. specifying them as URL). Alternatively you could disable the new option, or even create your own sprite icon image with the command line tool included in the package. For more information see the theme configuration option.
• #6023: It is now possible to specify authentication information like cookies, additional headers or basic authentication credentials in the client side configuration. This information will then be set on connections made from the Nimbudocs Editor server and can be used to e.g. load documents, images or CSS files from repositories which require authentication.
• #6037: Added an event/callback which is triggered when the caret reaches the document start/end.
• #6105: Added an event/callback (onselectionchange) which is triggered when the selection changes. It provides the current selection as plain text.
• #6121: It is now possible to localize the "default" list properties image (ul and ol).
• #6217: Added "mod_rewrite" module to the Jetty application server in the VA, which allows to configure "HSTS".
• #6227: The tool bar can now be updated/changed dynamically (new methods "getUIConfig" and "updateUIConfig").
• #6238: Introduced new configuration option for auto correct. The property "sentenceStartUpperCase" can now be set to "latinOnly". This limits the upper case correction at the sentence start to words that begin with a Latin letter.

Improvements

• Improved editing performance in IE and/or virtual environments.
• Reduced server-side memory footprint of the editor by improving handling of images contained in the document.
• Improved reliability of closing editor sessions (active closing by "leave()", closing the browser (tab) and passive closing by session timeout).
• Webmin Admin Interface: The list of editors now displays the date and time of the "Last Seen" attribute (Which is the time stamp of the last request from the client to this editor). The "Last Seen" attribute is used to determine when editor sessions have to be closed due to inactivity (session timeout).
• Automatic hyphenation (through CSS property "hyphens: auto") can now be used in Nimbudocs Editor.
• Improved behavior of shapes:
  • Shapes now snap to the document borders or to one another.
  • Added new side bar pane to change properties of shapes.
  • Box shapes can now be rotated.
  • Inserting and moving shapes is now more intuitive.

Bug Fixes

• #6001: Short cuts like e.g. Command + B now work again in Safari on OS X.
• #6008: Table handles are now displayed in the correct order for tables having colspan on some rows.
• #6069: It is now possible again to type in the editor after closing the search bar (in IE).
• #6141: Tables containing rowspan are now correctly displayed if spanning over two pages.
• #6145: The "defaultBaseUrl" configuration option is now correctly applied for resources inserted with "insertContent()".
• #6165: Improved caret positioning in tables when typing and changing the caret position rapidly.
• #6171: The editor is now displayed correctly when using the "retry()" method of the "onsessionlimitreached" callback.
• #6267: The editor now loads correctly even if "localStorage" cannot be accessed.
• #6269: Dialogs are now displayed correctly when the connection is slow

Changes

• "Copy" is now an asynchronous 2-step process:
  • Pressing the copy or cut button or using the appropriate shortcut now displays a dialog
  • Depending on the browser, a button or shortcut can be used to complete the copy or cut process
  As a result Copy & Paste is now possible through the tool bar buttons. Furthermore, as the "Copy" process is now asynchronous, this also solves the issue with using "Copy" in a load balancer scenario.
• Updated Java to 1.8.0_77 in the VA.

Release 2.2.3301 (released 2016-02-15)

Bug Fixes

• #5999: Fixed issue with deleting rows when a table containing table cells with the "rowspan" attribute is split in a specific way over two pages.
• #6026: Fixed issue when adding a row to a (nested) table when the inner table splits over multiple pages and has the style "border-collapse: collapse".

Improvements

• Improved general editor stability.
• Added a mechanism which tries to recover the editor in case an internal (server) error occurs. The mechanism will undo changes made in the editor until the editor is recovered or there are no more undoable changes. There is a new "onrecover" callback which is triggered in case the new mechanism steps in. By default the callback displays a dialog with information about the error and which step was undone.

Changes

• Removed the "workerThreadsCount" and "workerThreadsAbsolute" context init parameters, as they are no longer relevant.
• Added a mechanism to limit the maximum amount of concurrent editor sessions. The amount of concurrent editor sessions will now by default be limited by the memory available to the Nimbudocs Editor application server. It can be overridden by setting the "concurrenteditorsessions" context init parameter.
  Please note that increasing the amount of concurrent editor sessions above the calculated default maximum can result in decreased performance or even application server crashes!
  The amount of concurrent editor session can also be limited by the licensekey (the minimum of either default/context init parameter value or limit determined from the license key will be used). The limit (and its cause) will be logged on the INFO level on startup of the server.
• Added client side mechanism (callback) to handle the situation that there are no free editor sessions available.
• The MARTHA HTML/CSS layout engine and the PDFreactor version used internally (for printing/creating PDFs inside the editor) were synchronized with the PDFreactor 8 maintenance release version (8.0.8234).

Release 2.2.3284 (released 2015-11-09)

Bug Fixes

• #5965: It is now possible again to edit headers/footers in the page properties dialog.
• #5970: The retriever now also sends credentials (like e.g. cookies used for a load-balancer) when sending resources to the server.

Changes

• The MARTHA HTML/CSS layout engine and the PDFreactor version used internally (for printing/creating PDFs inside the editor) were synchronized with the PDFreactor 8 release version (8.0.8064).

Release 2.2.3273 (released 2015-10-21)

New Features

• #5898: It is now possible to specify a start value for an ordered list in the list properties dialog.
• #5951: Added API methods to retrieve/set the page properties (like e.g. page size, margins, header and footer - similar to what is possible using the page properties dialog).
• Added "onconnectionstatechange" callback. This new callback receives an event object, containing the boolean state of the connection (connected: true/false) and a string state indicating additional connection information.

Improvements

• Improved loading time of the editor (startup of the editor with an empty document).
• The client-server communication is now more robust and errors/problems on the server should no longer lead to a "disconnected" state on the client.
• Improved logging on server and client-side. The documentId of the current editor session is now displayed as identifier in the client and server-side log output.
• #5895: The zoom widget was improved as follows:
  • The 100% action button is now highlighted, when at 100% zoom.
  • When changing the zoom level a tool tip/indicator shows the current zoom-level.

Changes

• Updated Java version to 1.8.0_60 in the virtual appliance.
• Updated Jetty version to 9.3.2 in the virtual appliance. Jetty 9 will be installed in a different directory (/ro/jetty9/) than the previous version (/ro/jetty/) when updating.

Bug Fixes

• #5775: IE 11: The "x" displayed in a text field to "reset" the field is not compatible with Nimbudocs Editor and was thus removed (by CSS).
• #5795: Fixed paste behavior when a paste handler is configured.
• #5796: Selecting text by double clicking on a word now always works in IE.
• #5845: Selecting backwards over a <br/> between two paragraphs no longer disconnects the editor.
• #5857: The document now correctly scrolls to the selected change.
• #5861: The context menu is correctly placed when the document is scrolled.
• #5911: Resizing a video element no longer causes the editor to be non-responsive.
• #5931: Retrieving a resource from a host that does not exist no longer leads to a JavaScript error.
• #5949: Webmin interface: It is now possible to delete an API key with an empty description.
• #5950: Webmin interface: Added checkbox to disable the auto-refresh on the server control page (active client display).
• #5952: Typing accents or quotes using the "´" key is now possible.
• It is possible again to type and place the caret on mobile devices.

Release 2.1.3150 (released 2015-07-03)

New Features

• #5293: Tables (and its rows and columns) can now be resized using handles (mouse).
• It is now possible for the integrator to load and save the userpreferences. By default userpreferences are saved in local storage, which is browser and domain based. For users accessing the editor from multiple browsers or different locations this might not be optimal. Thus a configuration option "userPreferences" for loading userpreferences and a callback "onuserpreferenceschange", which is triggered when the userpreferences change, was added.

Improvements

• #5105: "margin:right" is no longer applied to a table which was resized using the new table handles.
• #5773: The "cut" and "copy" actions are only enabled when there is a selection.
• #5779: Improved cache killer mechanism for situations where two or more integration URLs are using the same server (e.g. dev and production) in the same browser session
• #5774: The context menu and its submenus are now as wide as their corresponding content. Improved opening of submenus (will open to either side depending on the available space).

Bug Fixes

• #5561: Context of floated images is now respected.
• #5562: Splitting and merging tables containing a tbody element no longer causes problems.
• #5776: Custom (user defined) auto-correct entries are now correctly saved/displayed.

System Requirements

Browser Support

The following browsers are supported:

• Edge
• Chrome 70+
• Firefox 63+
• Safari (OS X only) 12+
• IE 11+^*

^* Support for IE 11 is deprecated and it is not recommended to use Nimbudocs Editor in IE 11 as there might be issues with Nimbudocs Editor which only occur in IE 11.

The create() provides functionalities to react to non-supported browsers. Please see the Quick Integration Guide in the JavaScript API doc for more information.

Please note that development previews of supported browsers may not be able to run Nimbudocs Editor, even if the requirements check in JavaScript reports otherwise.

• CSS 3 2D Transforms (for zoom functionality)
• HTML5 APIs
  • File
  • Local Storage
  • Fullscreen

Server Minimum Hardware Requirements

This chapter holds information for integrators who do not use Nimbudocs Editor as a Service.

• 2 GHz Single Core or 1.5 GHz Dual Core CPU
• 4 GB RAM

In general, hardware requirements depend very much on the platform, the speed of the JVM implementation and the complexity of the documents which are edited.

Nimbudocs Editor as Virtual Appliance

Server Installation

The Virtual Appliance provides everything required to deploy a functional Nimbudocs Editor server as Virtual Machine.

Use the following URL for: VMWare vSphere, Oracle VM VirtualBox

https://repo.realobjects.com/download/beta/ovf/nimbudocs-va_OVF10.ovf

Additionally you need the vmdk file if you want to use VirtualBox:

https://repo.realobjects.com/download/beta/ovf/system.vmdk

If you want to use VMWare Workstation, Server or Player you can also download a compressed archive of VMX and VMDK files:

https://repo.realobjects.com/download/beta/ovf/nimbudocs-va.zip

Deployment of Nimbudocs Editor is supported on Oracle VM VirtualBox and VMware ESX. VMware ESX only requires the URL to the OVF file, VirtualBox requires both the ovf10 and vmdk file downloaded to the same folder.

Integration

Download the integration code & resources from the Nimbudocs Editor server and continue with the Integration Code & Resources chapter.

Nimbudocs Editor as Package

Contents

The archive release file contains this ReadMe and a pre-configured Jetty Application Server with the Nimbudocs Editor application.

Server Installation

The provided Jetty Application Server needs to be added to a host server.

To start, restart or stop the server on Unix-based systems run:

To start without the shell script, use start.jar:

System Requirements

Nimbudocs Editor provides a pre-configured Jetty Application Server. In addition Java is required. The following VMs are supported:

• Latest Oracle JRE 7 or 8 (JRE 8 is required if the pre-configured Jetty Application Server is used).

Integration

Download the integration code & resources from the Nimbudocs Editor server and continue with the Integration Code & Resources chapter.

Integration Code & Resources

The integration code & resources archive is available on the running Nimbudocs Editor server. It contains the following folders:

/doc/apidoc

This folder contains the JavaScript API documentation.

/samples/StandardSample

This folder contains the standard sample, including custom actions, localization and UI configuration.

The sample requires the URL to a Nimbudocs Editor server and will not run out-of-the-box. The sample will also not run from a file URL.

Current Limitations

Accessible Resources

External resources (e.g. images, CSS, ...) of documents to be loaded must be available to the server. The server must be able to reach their resolved URLs and download the data.

Mobile UI

Nimbudocs Editor currently provides no mobile user interface. It is intended to provide such an interface in the future.

Localization

It is currently not possible to set the locale file, it is only possible to add a locale extension.

Load Balancer

Using a load balancer and Collaboration is currently not supported.
