Bindings, Popup, NSValueTransformer

Hello,

I tried to search the archives. However, the two people who asked the same question got no response. It must be something simple.

I have an NSArrayController bound to an NSArray of NSNumbers. There is an NSPopupButton bound to the NSArrayController. The values display properly in the popup. However, the NSValueTransformer doesn't seem to be called on the objects (oddly, the reverse transformation is called on the selection).

Is there a trick to getting this situation to work? It's probably something simple, but I just don't see it.

NSArray of NSNumbers -> NSArrayController -> NSPopupButton -> contentObjects, contentValues (with transformer)

thanks,

Jaime Magiera
