问题 I'm using gwt-platform and tried to implement GWT's editor framework. But I don't get it working from within the presenter. There are some answers around the web, that say I have to inject the EditorDriver somehow into the Presenter, but I don't know how to do this... At the moment I tried this without success: public class MyPresenter extends Presenter<MyPresenter.MyView, MyPresenter.MyProxy> implements MyUiHandlers { public interface MyView extends View, HasUiHandlers<MyUiHandlers>, Editor

问题 There are examples where different kinds of objects are getting injected into a presenter, but I can't find an explanation how this can be done. In the Bootstrap-Code example they are injecting e.g. a SecurityDelegate object. Also in the Gatekeeper example I see things being injected, e.g. MyGatekeeper , but how is this done? What I want is to first check if the user is logged in and then create a CurrentSession object or something like this. But how can I pass/inject this object around? At

问题 I am new to gwt and I am creating a login page using gwt and I need help with session managment.

问题 We plan to use smart GWT, GWT and related frameworks for the client side rich interface and Spring MVC which returns JSON data on the server side. As part of the investigation to see if it fits our requirement, the following questions need some answers : Building a GWT application from scratch without using any frameworks will need considerable amount of effort to follow the standard MVP pattern.

问题 There are a bunch of questions like this. I went through most of them but none actually but I couldn't come up with any answer: I have a weird problem in one of my GWT/GWTP classes. The class compiles fine with the Eclipse compiler but fails with the javac compiler (Maven). //additional imports import com.gwtplatform.mvp.client.PresenterWidget; import com.gwtplatform.mvp.client.View; public class MyPresenter extends PresenterWidget<MyPresenter.MyView> { public interface MyView extends View {
