Description bkramer 2013-09-20 13:54:59 UTC

Description of problem:
It is not possible to compare datasource's configurations. I tried some other resources and compare configuration worked fine.

Version-Release number of selected component (if applicable):
RHQ 4.4.0

How reproducible:
Always

Steps to Reproduce:
1. Navigate to DefaultDS resource (on the left side) -> Configuration -> Current
2. Make a change in the DefaultDS;
3. In the Configuration -> History -> select two configurations and press "Compare" button; 

Actual results:
The screen will be dimmed and "Globally Uncaught Exception" will be displayed in the background. The only way to go get rid of this dimmed screen is to refresh the page. At the same time there are no exceptions logged in the rhq-server-log4j.log file and no messages logged in the Message Center. 

Expected results:
To have pop-up window that would display differences between two configurations.

Additional info:
This was tested with EAP 5.1.2.
