CoreData: Returning all the records for a parent object

Subject: CoreData: Returning all the records for a parent object
From: Chris Schmitt <email@hidden>

I have a core data model where an entity "group" is linked back to itself to allow groups to have sub groups..

Example:

Group A
   - Group B
   - Group C
Group D

Then I have a NSArrayController controller linked to retrieve detail records for each group. This is all working well. How do I retrieve all the detail records when the user clicks on the parent group.. Meaning if the user clicks on Group A I want the NSArrayController to be populated with all the detail records for A, B and C.

Thanks in advance.
