So there I was, chipping away, and suddenly I was mystified. Here's my situation:

I have 3 core data entities - I'll call them Lister1, Lister2 and TheListed. Both of the Listers have to-many relationships with TheListed.

I also have an NSTableView, whose columns' values are bound to the arrangedObjects of an NSArrayController looking at Lister1's list of related TheListed objects. I'll call that particular NSArrayController Lister1AC. I want the first column of this table to be checkboxes that are checked only if their row's corresponding object from Lister1AC is a member of Lister2's list of related TheListed objects.

I'm not sure how to do this. Any ideas? I'd be much obliged for a clean solution or a good reference. And yeah, I'm pretty sure I've looked through the salient sections of the Core Data Programming Guide. Something may have missed my eye though.

Plz advise!
