Popup windows

[Alex Shure]

Every time I fire RevealRootPopupContentEvent.fire(this, MyPopupPresenter)

I got error: com.google.gwt.core.client.JavaScriptException: (TypeError) : Cannot read property 'setPopupPositionAndShow_1_g$' of null Unknown.wrap_3_g$(Exceptions.java:36) Unknown.showAndReposition_0_g$(PopupViewImpl.java:156) Unknown.internalReveal_0_g$(PresenterWidget.java:520) Unknown.addToSlot_1_g$(PresenterWidget.java:188) Unknown.addToPopupSlot_0_g$(PresenterWidget.java:166)

Could someone please explain what is the right way of building popups?

Now I have next code:

in presenter:

 @Inject
    private AsyncProvider<PopupPresenter> popupPresenterAsyncProvider;

    @Override
    public void showPopup() {
        popupPresenterAsyncProvider.get(new WeblibAsyncCallback<PopupPresenter>() {

            @Override
            public void onSuccess(PopupPresenter result) {
                if (result != null) {
                     fireRevealRootPopupContentEvent(result);
                }
            }
        });
    }
    private void fireRevealRootPopupContentEvent(PopupPresenter popupPresenter){
        RevealRootPopupContentEvent.fire(this, popupPresenter);
    }

PopupPresenter extends PresenterWidget<PopupPresenter.PopupPresenterView>

PopupView extends PopupViewImpl<C extends UiHandlers>
in ui.xml I'm using com.sencha.gxt.widget.core.client Dialog
GWT - 2.7
gwtp  -1.4

PS: after I close exception message and make some UI manipulations, this popup is shown. After I press close popup button, page stop response and chrome tab takes 1.5 Gb memory

SetPopupPositionAndShow is a method in com.google.gwt.user.client.ui.PopupPanel

If you're using PopupViewImpl then you have to use it with a widget that extends from PopupPanel, which the gxt Dialog doesn't.  

You can use the PopupView interface with other kinds of dialogs but you'll need to do a custom implementation.
