liveuser_admin question about groups...

The following to me seems like it inforces a 1 to 1 relatinoship between child groups and parent groups.... is that right? assignSubGroup (line 122<http://220.237.136.132:1999/generatedpeardocs/LiveUser//__filesource/fsource_LiveUser_Admin__LiveUserAdminPermComplex.php.html#a122>) Assign subgroup to parent group. First checks if groupId and subgroupId are the same then if the child group is already assigned to the parent group and last if the child group does have a parent group already assigned to it. (Just to difference between what kinda error was hit) If so it returns false and pushes the error into stack - return: false on error, blah on success - access: public mixed assignSubGroup (array $data) - array $data
