Is it possible to transfer list of EntityProxy between client and server using Requestfactory

[July]

HI:

Just like below, Is it possible to transfer list of EntityProxy between client and server using RequestFactory? i didn't see any spec related to this in RF doc. And i always get NPE when using maven processor plugin to validate. Thanks.

@Service( value =foo.class, locator = bar.class )

public interface CustomerRequest extends RequestContext

{

    Request<Long> count( List<String> searchparams, List<MyEntityProxy> parent );

}

Problem solved, turned out to be the polymorphism problem.
