I have two Vibe instances. My test instance is 3.4, upgraded from 3.3 on Windows 2008 R2. My production is a newly installed 3.4 on SLES 11 SP3. On the production system, when I open the workflow editor in Form/View Designers, I get see the Sun Java loading icon in the preview window. When it stops spinning, if I click the workflow, the elements list to the right is blank. When I click the Close button, I am logged out of Vibe. If I disable the java add-on in the browser, it works fine except without the preview of course. This happens with any browser, IE, Firefox or Chrome.

Editing a identical workflow on the test system works fine using the same browsers on the same workstation.

Has anyone seen anything like this? I don't get how the local java add-on works for one instance and not the other. Could the hosting OS be the problem or that one was upgraded and the other was a fresh install?
