> public int getId();
> public void setId(int id);
> public String getName();
> public void setName(String name);
> }
>
> public class UserImpl implements User {
> //An implementation with Hibernate annotation for instance

> @ApplicationState
> private User _user

> I have an InstanciationException (witch is normal, because Tapestry have no
> way to guess that it should instanciate UserImpl and it tries to instanciate
> an Interface).
>
> So my question is : is there a way to tell Tapestry to instanciate the right
> class and not the Interface (may be via contributing to some Service
> configuration or something ) ? Or should I wrote a simple data object that
