I am binding an NSMenuItem (via NSArrayController) with "Availability" ->
"enabled". Think of "Edit" only if 1 item is selected.
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?
Cheers,
Knut
