Look in the user defaults docs for "registering default values." Although you shouldn't need to in this case--as you saw an NSButton had no issue--but I have seen similar errors in bindings when an unexpected value is returned by a model object. So, I am not saying that you have to do this, I am saying that the first course of action is to guarantee that the value is explicitly and predictably defined before you use it. You can't debug what you don't know. > On 28 באוג 2012, at 21:53, Keary Suska wrote: > >> >> On Aug 28, 2012, at 9:28 AM, Motti Shneor wrote: >> >>> But when I'm trying to do this in my XCode 4.2 project, in a .xib file, I >>> experience several problems, and finally a crash on loading the .xib file. >>> >>> 1.
