Bindings don't handle aggregate/coalesce. You will need to do that yourself in the main or a mediating model. Observe the controller's selection (or table view notifications) to update on the fly.
Ah, OK. That's perhaps why I couldn't see how to do it with bindings ;-) This is already what my 'classic' datasource approach is doing, so maybe after all I might as well stick with it. Doesn't look like bindings will help give me much for free in this case.
Also not a bindings-supported behavior. Implement table view delegate methods to provide cells on the fly. You can apply formatters or transformers to force default values (if you can't do that at the model level).
Ditto. If I'm having to deal with this in the table delegate I may as well stick to my current design which does other things that way.
Thanks - even when the answer is 'can't really be done', it's useful to know, and exactly what I was after.
