I am writing a plugin for school project to create special type of group. I extended the ElggGroup with a new class let's say Committee. I have trouble listing the objects of type Committee. The committee objects when listed the url still points to them being as 'group' object. When I tried to edit these objects it goes to default 'group' edit page rather than my newly created page.

The objects listed show up with trailing brackets '( )' and hovering over them shows the message "

This entity cannot be displayed correctly. This may be because it requires support provided by a plugin that is no longer installed."

Help is greatly appreciated
