Hi John,
Thanks for the reply. Yes, it looks like I'm left with few options.
Cheers,
Ben.

The problem here is that mouse events are received by NSViews, and

doesn't seem to be a way to access the view of an NSMenuItem. Given
this,
there seem to be two options:
Skip bindings and manually handle validation based on a combination of
the
containing menu of a given item and the properties that the bindings
were
observing.
Make 16 separate menus, and bind those.
Neither of them seem very appealing, I'm sure.
Here's what I'm trying to do :
From a menu bar menu, I need to display a list of 16 menu items. Each
menu item has a submenu which is to display a common (with a fairly
complex hierarchy) NSMenu (defined in IB) where many of those menu
items have values and enables controlled via bindings. I need to set
those bindings differently depending on which of the 16 parent items
was chosen (no clicks - which doesn't help)
The problem I have is that I can't use menu delegation because I don't
get a notification each time one of the 16 menu items is selected -
the delegation seems to to use caching and therefore I can't set my
bindings correctly before displaying the common menu.
