I used the method described here on a project using NSTreeController and bindings to populate an outline view: http://blog.wilshipley.com/2006/04/pimp-my-code-part-10-whining-about.html I'm not aware of any changes to NSTreeController/bindings that would replace this approach, but I'm always ready to be pleasantly surprised. :-) _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
