I should have been more specific. What I have looks like:
popupButton.content -(Transformer)-> [arrayController].arrangedObjects
popupButton.selectedIndex --> [arrayController].selectionIndex
I have also tried:
popupButton.contentValues -(Transformer)-> [arrayController].arrangedObjects
popupButton.selectedIndex --> [arrayController].selectionIndex
In both cases, the transformer is passed an _NSControllerArrayProxy object
which wasn't what I was hoping for; I had hoped for an NSString. I could
probably dredge around in that object and find some methods to use but all the
docs say "don't use undocumented methods/classes" so my gut reaction is to try
another way.
Ben.
