The error is intermittent. Needs to navigate between the content repository and server group screen.
Sometimes, a wrong server groups is selected in the manage deployment -> content repository -> server groups screen.

Version-Release number of selected component (if applicable):
JBoss EAP 6.1.1

Actual results:
the pop up screen for remove confirmation shows other server group from the server group selected.

Expected results:
always remove the deployment file from the server group selected.

Additional info:
the error is intermittent, however, in a test of 10 minutes, I could reproduce the issue two times.
