Created attachment 798184 [details] the same group 3 times Description of problem: Organizational Unit Manager allows you to add the same group multiple times. It appears so in the list of groups. When you switch perspectives or refresh, only one group is visible. If the groups have a different owner set, which group (with which owner) stays? Please fix this, so that a group may only be added once. Version-Release number of selected component (if applicable): BPMS 6.0 ER3
