Consider a more standard approach: Two array controllers, one for each collection. I sense you don’t want to do that because you want only one item to be “selected”. That seems like an unnecessary restriction. You can have a set of geometric primitives, with a selection, and a separate set of labels, with a selection. True, the user can only edit one of these at a time, but the other selection doesn’t mind sitting idly by. Remember, nonstandard designs always end up taking way more development time than expected. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
