Proposed changes

Problem was that we were incorrectly returning null as the raw class (i.e virtual attribute type) in this case. The attribute type is derived from the target entity for Object accessors.

Changes have been submitted.

Reviewed by: Chris Delahunt

Tested manually through Eclipse. Existing Full regression test suite and extended test suite continue to pass.
