When a control is added to GROUP1 then update counters of GROUP1, GROUP2, ..., DEVROOT will be incremented. So the update_counter field of any group will tell how many "real" controls there are under the group and all of its child groups (not counting any of the group nodes).
Apparently there are some problems with handling of the parent chain. The algorithm seems to think that the chain is broken so it aborts before reaching DEVROOT.
