- Fixed exception handling in RetrieveWlbConfiguration action (exceptions of type other than Failure were silenced). - CA-339666: Fixed control flickering when showing the WorkloadReports dialog. - Retrieve the WlbConfiguration before attempting populating the controls. - If the dialog was launched requesting a certian report to be run, the report was not selected on the list. - Some refactoring to simplify the code.
