While this may fix your problem, I'd strongly advise against it.  
Calling textDidChange: in validateSelection *is* the right thing to  
do because the contents of the combo box did change after a user  
induced change (which is when textDidChange: should be called  
according to the docs). Other objects watching the contents of the  
combo box may in fact rely on the NSTextDidChangeNotification being  
sent.

The problem really is that NSComboBox's textDidChange: method should  
not perform text completion. Instead, text completion should only be  
performed when the user has entered text, so I think it would be more  
appropriate to override insertText: in NSComboBox and attempt text  
completion there.
