OK,  so I think you may have the metadata registered twice perhaps,
once dynamically and once statically. I say this because the class you
have an instance of is DynamicDataObjectImpl and not
AnyTypeDataObjectImpl.  I wonder whether a dynamic registration of the
schema is masking the registration of the static classes?
