As far as I can tell this control doesn't do anything.
This bug was previously known as http://jira.rhq-project.org/browse/RHQ-2341
Temporarily adding the keyword "SubBug" so we can be sure we have accounted for all the bugs. keyword: new = Tracking + FutureFeature + SubBug
making sure we're not missing any bugs in rhq_triage
close per gwt effort
