Hi,
I am getting the above exception while running the GWT application.
I am using Entity and EntityProxies.
Below is the code:
@Entity
@Table(name = "tlkpState")
public class State{
.................
}
@ProxyFor(value = State.class)
public interface StateProxy extends EntityProxy {
public String getFips();
public String getName();
EntityProxyId<StateProxy> stableId();
}
@Service(value = StateServiceImpl.class)
public interface StateRequest extends RequestContext {
Request<List<StateProxy>> getStates() throws Exception;
//Request<Void> getStates() throws Exception;
}
in widget.java
try {
clientFactory.getRequestFactory().stateRequestContext().getStates().fire(new
Receiver<List<StateProxy>>(){
@Override
public void onSuccess(List<StateProxy> response) {
// TODO Auto-generated method stub
System.out.println("on success");
}
@Override
public void onFailure(ServerFailure error) {
System.out.println("on Failure");
}
});
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
when i call getstate() method with return type void it is working fine.
but the same method with return type List<StateProxy> it is throwing the
following exception:
