Are you talking about having 2 array controllers -- an Animal array controller and a Fish array controller? If not, it's not clear what you mean by the words "select", "corresponding", "binding" and "selection". :) > The problem is the index counts for Animal and Fish won't be the same if a > Mammal is added. > > Is it possible to do this using bindings in interface builder? The answer is probably "no". The entity inheritance mechanism isn't really designed for this purpose. If you want to (actually or in effect) apply a filter to an array controller, you'll need an actual "animalType" property that you can test._______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
