I believe that you can get the desired effect by setting your enabled
binding's Multiple Values Placeholder to YES.
You can also set the No Selection Placeholder to NO. You probably
don't need the "@count" keypath; you can probably just use the Value
Transformer "NSIsNotNil".

I am binding an NSMenuItem (via NSArrayController) with

Controller Key is set to "selection"
Model Key Path is set to "@count"
Works fine, but my goal is to enable the NSMenuItem only if 1 (and
only 1!)
item is selected in the NSArrayController. NSMenuItem remains
enabled if
several items are selected.
I've tried virtually every combination of Key and Path settings
that looked
promising to no avail. Someone out there to enlighten me?
