[aida] addMenuAspect:collection:selectedToAspect:of:

Can I send an event after an item in the menu is selected ? I want 3 menus 
on 1 form and the collection of the 2nd menu is dependent on the selection 
of the first menu. The collection of the 3th menu is created after you know 
what was selected in the 2nd menu.
