On MacOSX valdiateEditing is called from here:

#0  0x9313e878 in -[NSControl validateEditing] ()
#1  0x931400b8 in -[NSActionCell attributedStringValue] ()
#2  0x930bb6a8 in _NXDrawTextCell ()
#3  0x930c8180 in -[NSTextFieldCell drawInteriorWithFrame:inView:] ()

Until this is properly figured out, I have changed the above method 
(temporary hack) as follows, since the above caused problems with date 
formatters.

- (void)textDidChange: (NSNotification *)aNotification
{
   NSMutableDictionary *dict;

   // validate NSNumbers immediately so that objectValue returns 
reasonable values in controlTextDidChange:
   if ([(NSFormatter *)[_cell formatter] 
isKindOfClass:[NSNumberFormatter class]])
     {
      [self validateEditing];
     }

    ...
}

Regards,
