Whenever possible, manipulate relationships directly. Perhaps you do this, but
the code isn't shown. If your array controller is bound to the relationship,
you shouldn't have make any calls to it at all. It will update itself. If it
isn't updating, it means you aren't using your relationships properly.

I would need to know what the -add* methods do to make any suggestions. Chances
are, these methods are not updating the relationships properly.
