GWT 2.4.0 RequestFactory polymorphism

Question

Does GWT 2.4 support this case:

@Entity class MyBase {...}
@Entity class MyChild1 extends MyBase {...}
@Entity class MyChild2 extends MyBase {...}
...
@ProxyFor(         


        

Answer 1

Fixed it with @ExtraTypes:

@Service(ArticleBase.class)
@ExtraTypes({MyChild1Proxy.class, MyChild2Proxy.class})
public interface MyBaseRequest extends RequestContext {
    Request<MyBaseProxy> getStuff(); // MyChild1 here
}
