When I create a new application for macOS, not document based, using CoreData, and bind an ArrayController to File's Owner persistentContainer.viewContext, I get the following exception:
2017-09-18 12:53:17.525295+0200 Parlament[1349:76421] [General] An uncaught exception was raised

Does anybody know the right binding for the controller?
