No one a suggestion on how to track this down?

I have a custom NSCollectionViewItem

   @end

It's getting filled via core data just fine. Then I've also bound the filterExpression to the NSTextField in the prototype view. The same way the button is bound.

   @implementation FilterViewItem

   - (IBAction) applyFilter:(id)sender
   {
       NSString *expression = [filterExpression stringValue];

       NSLog(@"expression %@", expression);

When the button is pressed it turns out that filterExpression (and therefor also the stringValue of it) is nil.

I assume somehow I could probably also get the value from the NSArrayController ...but

a) I am not sure how to get hold of the instance from within the FilterViewItem

b) I would need to get access to the NSTextField at some stage anyway

What am I missing here?
