What I will often do in these cases is bind "enabled" to a keypath that I know will always be non-nil, and use the NSIsNotNil transformer. I then set the "No Selection" and "Multiple Selection" placeholders to "No". May be kludgey, but it works. P.S. to be safe, you could also set the "NULL" placeholder to "Yes", just in case null/nil values are possible. > On Jun 18, 2008, at 12:23 PM, Eloy Duran wrote: > >> Hi list, >> >> I have a NSArrayController and a form (collection of controls) that >> displays attributes for a individual object in the array controller. >> One attribute is bound to a NSMatrix (radio buttons) with the >> "Selected Index" binding.
