NSSearchField Categories Menu (bug?!)

Hi list,
I would to add a categories menu (ex: search for Subject, Body or ...)
in my NSSearchField. I've successfully set the menu but there is a
problem if I try to set a menuitem to state:NSOffState.
When I select a menu it should be to turn off the previous selected
category. This is the code:

- (IBAction) menu_selectNewFilter:(id) sender {

   NSMenuItem *m = [searchMenu itemWithTag: selectedFilter];
   [m setState: NSOffState];
   NSLog(@"Disabled %@ %d",[m title],[m tag]);
   
   NSLog(@"Activate %@ %d",[sender title],[sender tag]);
   [sender setState: NSOnState];
   
   selectedFilter = [sender tag];
}

It works for ONState but the previous item state will never change
(I've also tried to take a look at the debugger and, in fact the state
of NSOffState menuitem is 0...but the checkmark icon still here!).
Is there a problem with this class or is it a problem of mine?
