- Moved common CPArray/CPSet collection KVC operators to _CPCollectionKVCOperators.
- Implemented KVC operator dispatch using Objective-J.
- Fixed infinite loop with empty collection in @min, @max and @sum operators.
- Correctly return valueForUndefinedKey when necessary.
- valueForUndefinedKey reason uses raw description for consistency, class' overridden description may not helpful at all.
- Don't create a forwarder for @ operators with property paths.
- Fixed CPSet -valueForKeyPath to correctly deal with nil/undefined/empty values.
- Added tests for collection KVC operators.
- enumerator -nextObject should always compare against nil for clarity, correctness, and consistency.
- setValue:forKeyPath will now get call setValue:forKeyPath again on the value of the first part of the key path
- override valueForKeyPath: and valueForKey: in CPObjectController's CPControllerSelectionProxy to return controller markers when appropriate
- override setValue:forKeyPath: and setValue:forKey: in CPObjectController's CPControllerSelectionProxy to bypass possible controller markers
This commit also removes previous hacks for compound paths and adds test cases for the errors. All this is related to issue #967.
