That's the conclusion I came to but wanted to make sure I didn't miss something obvious. The documentation is omitted this detail. I'll file a bug for this.
For the life of me, I cannot understand why NSToolbarItem contains the view and is not derived from a view, it just adds more work on the developer to do custom work. I wanted to do some work and need to track the mouse messages. It would have been much simpler if it was derived from the view and I could over-ride the methods.
