带参数的PlaceRequest到Popup Presenter

Question

我试图将placerrequest中的参数传递给一个将是弹出式的演示器，但是，我在弹出式演示器中接收空参数。我忘了什么吗?

AddProjetoPresenter

public class AddProjetoPresenter extends Presenter<AddProjetoPresenter.AddProjetoView, AddProjetoPresenter.AddProjetoProxy>
    {
    @ProxyCodeSplit
    @NameToken(NameTokens.addproj)
    public interface AddProjetoProxy extends ProxyPlace<AddProjetoPresenter>
    {
    }
    public interface AddProjetoView extends View
    {
        HasValue<String> getNome();
        HasValue<Date> getDtInicio();
        HasValue<Date> getDtFim();
        HasClickHandlers getAddRequisitos();
        HasClickHandlers getAddStakeholders();
        HasClickHandlers getBtCancelar();
        HasClickHandlers getBtSalvar();
    }
    private final DispatchAsync dispatch;
    private final PlaceManager placeManager;
    private Projeto projeto;
    @Inject
    public AddProjetoPresenter(final EventBus eventBus, final AddProjetoView view, final AddProjetoProxy proxy, final DispatchAsync dispatch,
            final PlaceManager placeManager)
    {
        super(eventBus, view, proxy);
        this.dispatch = dispatch;
        this.placeManager = placeManager;
    }
    @Override
    protected void revealInParent()
    {
        RevealContentEvent.fire(this, MainPresenter.TYPE_SetMainContent, this);
    }
    @Override
    protected void onBind()
    {
        super.onBind();
        getView().getBtSalvar().addClickHandler(new ClickHandler()
        {
            @Override
            public void onClick(ClickEvent event)
            {
            }
        });
        getView().getAddRequisitos().addClickHandler(new ClickHandler()
        {
            @Override
            public void onClick(ClickEvent event)
            {
                PlaceRequest pr = new PlaceRequest(NameTokens.addreq);
                pr.with("oi", "oiiiii"); // HERE
                placeManager.revealPlace(pr, false);
            }
        });
    }
}

AddRequisitoPresenter

public class AddRequisitoPresenter extends Presenter<AddRequisitoPresenter.AddRequisitoView, AddRequisitoPresenter.AddRequisitoProxy>
{
    @ProxyCodeSplit
    @NameToken(NameTokens.addreq)
    public interface AddRequisitoProxy extends ProxyPlace<AddRequisitoPresenter>
    {
    }
    public interface AddRequisitoView extends PopupView
    {
        DialogBox getDialog();
    }
    private final DispatchAsync dispatcher;
    private Projeto projeto;
    @Inject
    public AddRequisitoPresenter(final EventBus eventBus, final AddRequisitoView view, final AddRequisitoProxy proxy, final DispatchAsync dispatcher)
    {
        super(eventBus, view, proxy);
        this.dispatcher = dispatcher;
    }
    @Override
    public void prepareFromRequest(PlaceRequest request)
    {
        super.prepareFromRequest(request);
        getView().getDialog().setText(request.getParameterNames().size() + ""); //SIZE IS ZERO!!
    }
    @Override
    protected void onBind()
    {
        super.onBind();
    }
    @Override
    protected void revealInParent()
    {
        RevealRootPopupContentEvent.fire(this, this);
    }
}

我想我做错了什么…

根据我在wiki上的理解，一个弹出窗口不能是一个地方，它需要一个父演示器。

我看到两个明显的问题:

• 你的第二个演示器(弹出窗口)应该实现PresenterWidget，而不是presenter
• 你不能通过调用placeManager.revealPlace()来显示弹出窗口，因为弹出窗口不是一个位置。相反，您必须应用wiki中解释的两个方法之一(addToPopupSlot()或revealrootpopupcontenttevent .fire()，两者都是从父调用的)。
