You can't have the same item in two places in an NSOutlineView.

You're going to need to use separate item objects for the two appearances of 'Cocoa', even though they both refer to the same object in your model. You can do this by making an 'OutlineItem' class that has a single property that points to your model object. Then your data- source methods will wrap each model object in an OutlineItem before returning it to NSOutlineView.
