title: Binding NSArrayController to moc in NSPersistentDocument subclass in Xcode4 in XIB view
body: <p>I have my subclass of NSPersistentDocument who's superclass has [self managedObjectContext]</p>
  
  <p>Trying to set the bindings of my NSArrayController in the xib. When I set the Parameter's Moc, the bind to choices are: File's Owner, App, and Prefs. (The NSArrayController's entity is set to the Entity name in my context)</p>
  
  <p>Model KeyPath defaults to self.
  I then bind the value of a table column to the NSArrayController (Which I'm not sure how to rename under Xcode 4).arrangedObjects.(name of my entity property)</p>
  
  <p>There's a populate button on the UI to self populate the context.</p>
  
  <p>When I run. The UI won't come up and all I get in the console is repeated:
  -[MyDoc persistentStoreCoordinator]: unrecognized selector sent to instance 0x10015adf0</p>
  
  <p>Suggestions?</p>
