#507: valueForKey(key) no longer working with NSManagedObject subclasses.
-----------------------------------+----------------------------------------
Reporter: johnmacs...@… | Owner: lsansone...@…
Type: defect | Status: new
Priority: major | Milestone:
Component: MacRuby | Keywords: valueForKey, KVC, Core Data
-----------------------------------+----------------------------------------
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.
