Codegen tool for DTO models

Has anyone encounter a DTO model where the forceNonHandleType=true was not working?
My EClass has a teamReference attribute with a the key/value set but the generated implementation class is using the handle.
I also tried putting the key/value in a teamAttribute attribute but that did not work either.
Any thoughts?
Thanks.
