Hello guys,
I have an exception in the following code using the MVP pattern. I'm
just iniciaiting myself to the GWT world and I would need some help.
Call:
public class LoginActivity extends AbstractActivity implements
LoginView.Presenter {
private ClientFactory clientFactory;
[...]
public void goToControlPanel() {
clientFactory.getPlaceController().goTo(new
ControlPanelPlace("controlPanelPlace"));
}
Stack trace:
