Fixes the reported issue with a hacky workaround of not wiring in the attribute driver. I've hit too many brick walls trying to make the annotations/attributes drivers support null returns (decorating drivers expect non-null returns, hierarchical stuff breaks without a metadata object being returned), so until everything can be made to work correctly without these drivers always creating a metadata object, this is the quickest solution.
