Perhaps I'm missing something obvious... Given a MenuBar defined by this XML:
<menuitem> <menuitem label="A"> <menuitem label="AA"> <menuitem label="AA1" instanceName="inAA1"/> </menuitem> </menuitem> </menuitem> How can I zero in and operate on an arbitrary menu item (like that with instanceName "inAA1"), e.g., to enable or disable it? And is the 'instanceName' attribute useful for anything other than discrimination in a switch statement in a menu's event handler?
