I'm trying to use bindings to hook up my model to an NSOutlineView, and I'm attempting to use the countOf<Key>, objectIn<Key>AtIndex_ methods to do the KVC half. The problem I'm running into is that I'm getting None for the index argument, and I can't figure out what to do with that. The reference materials[1] say that the method corresponds to the NSArray objectAtIndex: method, which takes an NSUInteger, but doesn't mention anything about null or nil or whatever it is in objc-land.
