Unrelated note: you need to assign self = [super initWithWindowName:
…].
- (NSManagedObjectContext *)managedObjectContext
{
return [[self document] managedObjectContext];
If you're doing this why do you have an ivar?
In the running application the auxiliary panel displays properly but
an error message is produced: "Cannot perform operation without a
managed object context".
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.
