My code here came out of Hillegass Third Edition Chapter 12. I will need to think about this.

Because you have a managedObjectContext ivar, you never change its value so it defaults to nil, and +[NSObject(NSKeyValueCoding) accessInstanceVariablesDirectly] returns YES, -[AuxPanelController objectForKey:@"managedObjectContext"] will always return nil. Ditch the ivar.

Yes I see your point. Ditched the ivar but still get "Cannot perform operation without a managed object context" error. Must be some other reason why the binding is not working.
