I was more interested in whether myArrayController is nil when -
becomeFirstResponder is called. The NSLog below won't tell you that,
so I wasn't sure if you specifically checked for nil.

I've created a subclass of NSDatePicker to catch when a date
picker has focus. I have overridden the becomeFirstResponder
method and indeed it detects when it has focus. The code inside
the method does work except for any IBOutlets that I may have
connected. They don't respond to any requests.
I have verified that the IBOutlets are connected by adding a
separate IBAction in the subclass and a simple button to invoke
the action. Inside the IBAction I can call the same IBOutlets
successfully.
I am baffled as to why when the IBOutlets are inside
becomeFirstResponder they don't seem connected. Example below...
-(BOOL)becomeFirstResponder // myArrayController will not respond
{ NSLog(@"DetectDatePicker:firstResponder: %i",
[[myArrayController arrangedObjects] count]);
return YES;
}
-(IBAction)detectPicker:(id)sender // myArrayController
successfully responds
{ NSLog(@"DetectDatePicker:performClick: %i",[[myArrayController
arrangedObjects] count]);
}
Have you checked whether myArrayController is nil, just whether it
has content? Those would likely be two separate issues...
