Validating NSControl

I'm new to the list... forgive me if this was asked yesterday or somesuch.

All right... I got a NSControl to validate its input, but I can still press the OK button in my dialog even when I enter fotzed text into the control (specifically a NSForm tied to a NSNumberFormatter).

What would be nice is a method in NSControl like -(BOOL)isValid, then I could call that from the delegate / notificatoin method -(void)controlTextDidChange:. Apple's docs relating to this are definitely not thorough, and I can't find any sample code.

Am I missing anything obvious?
