Cocoa does not support binding to view properties like this. Most are not KVC compliant.
But you can make them KVO-compliant as I described yesterday. It's a slight kludge, but I think of it as a necessary "bridge" from the old world of dataSource to the new world of bindings.
So, if you are already using NSTreeController, observe it instead of NSOutlineView. Otherwise, either replace your dataSource with NSTreeController, or else use the bridge/kludge.
