NSCollectionView and Core Data problem

Subject: NSCollectionView and Core Data problem

Hello...

I have an NSCollectionView that I am trying to use with Core Data and I can't seem to get the view to actually display data.

I have an NSArrayController and I'm doing a fetch and populating the controller using its setContent method. The controller is bound to the NSCollectionView's content binding and the controller key is arrangedObjects.

The prototype view contains only an NSTextField. Its value is bound to the Collection View Item and the key path is representedObject.name. (The objects in the array controller have a "name" attribute.

I've used gdb and the controller is content is populated and it appears to be bound correctly. The problem is that the text field doesn't appear in the collection, not even empty ones.

Any ideas? I think the prototype automatically sets its represented object based on the controller bound to the collection. Is that correct?

Any help would be appreciated.  Thanks,

Adhamh
