5.3. Document Viewer

The viewable document types

The Documents application allows users to build custom content types and provides some built-in content types. It also provides a viewer for common file types so that users can read an Office document, view an image or play a video.

So the following types are viewable:

For the viewable types, when you click a document preview thumbnail in the Activity Stream, or when you select View Document menu from Documents in the left navigation, the Document Viewer opens with a large view area and provides some functions, such as Search, Download, or Print.


To exit the Viewer, hit Esc key or click X icon at the top right corner.


The Comment pane where you can comment or like a post is available only when you view a document from Activity Stream.

If the document is an unknown type, you need to download it to your local machine and open it by another application.

PDF and Office documents

You can always view a pdf file, whereas Office documents require JODConverter to be installed in the server, so ask your administrators if you cannot view a MS Word file for example.

For these types, the Document Viewer gives a maximized reading estate and all the functions listed.

You can simply scroll to go to another page, but it gives many page selectors (previous, next, first and last page links, page number selector). You can also show/hide a Page Thumbnail pane by clicking the leftmost icon in the toolbar (click it again to close).

Images, Audios and Videos

For viewable media types, the available functions are Download, Comment and Like.


Audios/Videos playback may require appropriate browser plugins. If you see a message like "Video format or MIME type is not supported", it indicates that you may need to install or enable some plugins for that media type.

ECMS Content

If the document is an ECMS Content type, it is viewable. The following screenshot is an Illustrated Web content (one of built-in templates).
