 In MacRuby 0.4 - any method in an NSManagedObject subclass (or in any
 other class) could be bound (eg via a controller) to a (view)
 nscontroller/field.

 Now - in 0.5 beta 1 and 2 (unless a variable of the same name is a
 property in the Entity that the NSManagedObject represents)
 valueForUndefinedKey(key) is called in the subclass, if that method
 exists, or an error occurs (if valueForUndefinedKey(key) does not exist) -
 eg: [<Student 0x200391280> valueForUndefinedKey:]: the entity Student is
 not key value coding-compliant for the key "age".

 This does not occur in a non NSManagedObject subclass - when view objects
 are bound to other classes' methods(attributes) - it all works fine.

 The different version of NSManagedObject valueForKey could be the culprit
 vis a vis valueForKey in NSObject, but in any case - as mentioned - it
 worked fine in 0.4.

 Example project attached.
