Luckily I haven't touched the UI. I just used the pl/sql apis.
What I did was create group-types because each different kind of group I am usig is going to be an object-type anyway. So i figured that using the group-type object-type was the best solution in that case as opposed to linking my object_type specific table to the group through a group_id column. Also this application will have multiple groups of each group type.
