If you're targeting Leopard, you can force the tree controller to -
fetch: (so it's updated) then I believe you can ask the outline view
for its -rowForItem: ... if you're targeting Tiger, it's not as
straightforward due to proxy objects.
I am targeting Leopard (for now, at least). However, -rowForItem:, and
for that matter, -itemForRow: both return null, even if I fetch first.
