Have you considered just implementing the outline view delegate method outlineViewSelectionDidChange() and, in there, using treeController.selectedObjects[i].range to highlight the matches in the source text view? Bindings are great if they happen to make things easier/simpler, but sometimes it's easier/simpler to go another route.
