SmartGWT WindowとPresenterWidgetを使用したGWTPエラー

Question

SmartGWT 3.0とGWTP 0.7を使用しています。

SmartGWTウィンドウを表示する簡単なPresenterWidgetを実行しようとしています。これは、ウィジェットのプレゼンターのためのコードです：

import com.gwtplatform.mvp.client.PresenterWidget; 
import com.gwtplatform.mvp.client.PopupView; 
import com.google.inject.Inject; 
import com.google.web.bindery.event.shared.EventBus; 

public class DemoWidgetPresenter extends 
    PresenterWidget<DemoWidgetPresenter.MyView> { 

public interface MyView extends PopupView { 
} 

@Inject 
public DemoWidgetPresenter(final EventBus eventBus, final MyView view) { 
    super(eventBus, view); 
} 

@Override 
protected void onBind() { 
    super.onBind(); 
} 

@Override 
protected void onReveal() { 
    super.onReveal(); 
    System.out.println(">>>> onReveal()"); 
} 
} 

そしてビューコード：

import com.gwtplatform.mvp.client.PopupViewImpl; 
import com.google.inject.Inject; 
import com.google.web.bindery.event.shared.EventBus; 
import com.google.gwt.user.client.ui.Widget; 
import com.smartgwt.client.widgets.Window; 
import com.smartgwt.client.widgets.events.CloseClickEvent; 
import com.smartgwt.client.widgets.events.CloseClickHandler; 

public class DemoWidgetView extends PopupViewImpl implements 
    DemoWidgetPresenter.MyView { 

private Window winModal; 

@Inject 
public DemoWidgetView(final EventBus eventBus) { 
    super(eventBus); 

    winModal = new Window(); 
    winModal.setWidth(300); 
    winModal.setHeight(500); 
    winModal.setTitle("Export file"); 
    winModal.setShowMinimizeButton(false); 
    winModal.setIsModal(true); 
    winModal.setShowModalMask(true); 
    winModal.centerInPage(); 
    winModal.setCanDragResize(true); 
    winModal.addCloseClickHandler(new CloseClickHandler() { 
     @Override 
     public void onCloseClick(CloseClickEvent event) { 
      winModal.hide(); 
     } 
    }); 
} 

@Override 
public void center() { 
    winModal.centerInPage(); 
} 

@Override 
public void hide() { 
    winModal.hide(); 
} 

@Override 
public void setPosition(int left, int top) { 
    winModal.setLeft(left); 
    winModal.setTop(top); 
} 

@Override 
public void show() { 
    winModal.show(); 
} 

public Widget asWidget() { 
    return winModal; 
} 
} 

私はこのプレゼンターを表示し、プログラムの別の部分では： dpがあるaddToPopupSlot(dp, true);

注入されたDemoWidgetPresenterのインスタンス。

DemoWidgetPresenterはfolowing例外が発生示している。

私は問題が com.smartgwt.client.widgets.Windowと com.google.gwt.user.client.ui.PopupPanel間鋳造によるものですが、私はそれを解決する方法がわからない参照してください！ ..

任意のアイデア/回避策:-)を例外にもかかわらず

は、ウィンドウが表示されますが、機能onReveal()は呼び出すことはありませんので、プレゼンターライブサイクルが壊れていますか？

ありがとうございます！

私は、アダプタクラスをやって解決策を見つけた：

import com.google.gwt.event.logical.shared.CloseEvent; 
import com.google.gwt.event.logical.shared.CloseHandler; 
import com.google.gwt.event.shared.HandlerRegistration; 
import com.google.gwt.user.client.ui.PopupPanel; 
import com.gwtplatform.mvp.client.PopupView; 
import com.gwtplatform.mvp.client.PopupViewImpl; 
import com.smartgwt.client.widgets.Window; 
import com.smartgwt.client.widgets.events.CloseClickEvent; 
import com.smartgwt.client.widgets.events.CloseClickHandler; 

/** 
* Adapter class for {@link Window}. This class it is necessary when a 
* {@link PopupView} uses as widget a {@link Window}. GWTP library does an 
* explicit cast to {@link PopupPanel} in {@link PopupViewImpl} and a cast 
* exception is raised. This class adapts only these functions which are call in 
* {@link PopupViewImpl}. 
* 
* 
*/ 
public class PopupPanelAdapter extends PopupPanel { 

private Window delegate; 

public PopupPanelAdapter(Window delegate) { 
    this.delegate = delegate; 
    // adapting window close event 
    delegate.addCloseClickHandler(new CloseClickHandler() { 
     @Override 
     public void onCloseClick(CloseClickEvent event) { 
      CloseEvent.fire(PopupPanelAdapter.this, null); 
     } 
    }); 
} 

public void hide() { 
    delegate.hide(); 
} 

public void show() { 
    delegate.show(); 
} 

@Override 
public HandlerRegistration addCloseHandler(CloseHandler<PopupPanel> handler) { 
    return super.addCloseHandler(handler); 
} 

@Override 
public boolean isShowing() { 
    return isVisible(); 
} 

@Override 
public void center() { 
    delegate.centerInPage(); 
} 

@Override 
public void setPopupPosition(int left, int top) { 
    if (delegate == null)// call in constructor, delegate is null 
     return; 
    delegate.setLeft(left); 
    delegate.setTop(top); 
} 
} 

それが正常に動作します！

Answer 2

私の場合、レイアウトを定義するのにUIBinder XMLを使用していますが、私はGWTBootstrap3のModal compenentに問題がありました。

私が言及したソリューションを使用してカスタムModalPopupAdapterをロールアウトしたが、別の部分に以下の追加必要があった：ビューに

Javaコードを

@UiField(provided = true) 
Modal modal = new Modal(); 

@UiField(provided = true) 
ModalPopupAdapter modalPopupAdapter = new ModalPopupAdapter(modal); 

UiBinderサンプルメッセージのXML

<afr:ModalPopupAdapter ui:field="modalPopupAdapter"> 
    <bs:Modal ui:field="modal" other-attributes...>
