The usage of the Document Viewer Service v. 2.0.4 and Jahia Enterprise Document Viewer v. 2.0.3 modules does not work with the last plugin Flash Player version: v21.
The issue could be reproduced as below:

  • Create a site
  • Use the componentDocument preview and use a PDF file for the File property.
  • Publish the site
  • Access to the site in Preview mode
  • Check that the PDF file is not displayed


The embedded version of Flex in the "Document-management" module seems to be the version 11.

The embedded version of Flash Player in Chrome v50 is the version: 21.0

It seems this difference which prevents the display of the PDF file.

After disabling the Flash Player plugin (chrome://plugins), the PDF file is displayed (in HTML 5)


A new version of Document Viewer : document-viewer-ee-2.0.4-SNAPSHOT.jar has been released.

This version can only be used in Développement environment. Comment from https://jira.jahia.org/browse/QA-8654:

I tested again this morning on a new Jahia installation:
I just created a site "mySite" with the sample bootstrap template, went in edit and added a document preview content. In the file picker, I uploaded a pdf, then published the site.
I have the empty popup when accessing the site as a guest user when I'm logged as root or with a different user I don't have it.
And it happens on every
browsers I have (FF/Chrome/IE), as I have Windows 10. 

Therefore, the fix for the patched module document-viewer-ee-2.0.4-SNAPSHOT.jar does not seem to introduce the issue with the guest user.
I'll create a QA ticket to track this issue. Here is the link to the QA ticket: https://jira.jahia.org/browse/QA-8708
