How to reproduce 1. Go to Add new page 2. Enter some name, leave the layout empty 3. Switch View mode to Preview and drag & drop Application registry portlet to the layout. 4. You should see that preview of Application registry is broken. This bug affects only Chrome and Firefox, Safari is fine.
A similar thing happens with the Site Redirects portlet. I couldn't reproduce this with other portlets or gadgets. No errors in the log. Requests for some resources return HTTP 404: - ApplicationRegistryPortlet.png - RedirectsAndImportExportAdminPortlet.png Layout seems to be fixed by reloading the page. Also found in 6.1.1 and 6.1.0
I can reproduce issue in JBoss Portal 6.2.0 ER2, but I can not reproduce it on GateIn master/3.8.x branches.
The branding extension jpp-branding-extension.ear is responsible for this issue. I couldn't reproduce it on master/3.8.x but in JBoss Portal. I'm going to move this issue for ER04 and prepare a patch.
https://github.com/gatein/gatein-portal/pull/880 was merged in upstream.
I confirm that the issue has been fixed.
