Hi,Vojtech Szocs: Thanks for your help, I have let it work, The Error I got just because I miss the step 3 you noted. Another question is how could I got the returnValue after executeCommand , and let the returnValue display on the oher Popup dialog. ÔÚ 8/14/14, 0:07£¬ "Vojtech Szocs" <vszocs@redhat.com> ÐŽÈë:
Hi,
forgot to mention, one more thing needs to be done:
// in PresenterModule bindPresenterWidget(TemplateBackupPopupPresenterWidget.class, TemplateBackupPopupPresenterWidget.ViewDef.class, TemplateBackupPopupView.class);
(Above binds popup PresenterWidget/View within GIN DI context.)
Regards, Vojtech

Hi,
in order to add new dialog, follow these steps:
1, create UiCommon model for the dialog, I see you already did this (TemplateBackupModel) - however from your code I don't understand why is there an unused "_asyncQuery" inside model constructor
2, modify existing list model to trigger your new dialog, I see you also did this (second code snippet), I assume you put that code inside TemplateListModel:
// inside TemplateListModel#backup - this method should be private // since UI code executes this method via associated UICommand ... TemplateBackupModel model = new TemplateBackupModel(); setWindow(model);
model.setTitle(ConstantsManager.getInstance().getConstants().templateBack upTitle()); model.setHelpTag(HelpTag.template_backup); model.setHashName("template_backup");//$NON-NLS-1$ ...
now, expose UICommand that triggers your dialog like this:
public UICommand getTemplateBackupCommand() { return privateTemplateBackupCommand; }
private void setTemplateBackupCommand(UICommand value) { privateExportCommand = value; }
// inside TemplateListModel constructor ... setTemplateBackupCommand(new UICommand("TemplateBackup", this)); //$NON-NLS-1$ ...
// inside TemplateListModel#executeCommand ... else if (command == getTemplateBackupCommand()) { backup(); } ...
3, tell UI (GWTP) infra how to handle your dialog model - in this particular case, edit TemplateModule#getTemplateListProvider:
... if (lastExecutedCommand == model.getEditCommand()) { return popupProvider.get(); } else if (lastExecutedCommand == getModel().getExportCommand()) { return exportPopupProvider.get(); } else if (lastExecutedCommand == getModel().getTemplateBackupCommand()) { return templateBackupProvider.get(); } else { return super.getModelPopup(source, lastExecutedCommand, windowModel); } ...
now, add parameter to TemplateModule#getTemplateListProvider:
@Provides @Singleton public MainModelProvider<VmTemplate, TemplateListModel> getTemplateListProvider( ... final Provider<TemplateBackupPopupPresenterWidget> templateBackupPopupProvider) { ...
4, create PresenterWidget & View for your dialog, this is the visual part of the dialog (dialog model just encapsulates the dialog logic)
public class TemplateBackupPopupPresenterWidget extends AbstractModelBoundPopupPresenterWidget<TemplateBackupModel, TemplateBackupPopupPresenterWidget.ViewDef> {
public interface ViewDef extends AbstractModelBoundPopupPresenterWidget.ViewDef<TemplateBackupModel> { }
@Inject public TemplateBackupPopupPresenterWidget(EventBus eventBus, ViewDef view) { super(eventBus, view); }
}
---
public class TemplateBackupPopupView extends AbstractModelBoundPopupView<TemplateBackupModel> implements TemplateBackupPopupPresenterWidget.ViewDef {
// you can get some inspiration from VmExportPopupView
}
5, you are done :)

Hi, everyone: I add a button, named backup in the Template Tab, And the click event is ok. Now I want add a dialog after clicked the button, So, I add a model , but the dialog didn¡¯t display at all.
So, I want to know is there some necessary class need To modify or add?
The model code is like this: TemplateBackupModel.java ======================================================== public class TemplateBackupModel extends Model {
private EntityModel privatePassword;
public EntityModel getPassword() { return privatePassword; }
public void setPassword(EntityModel value) { privatePassword = value; }
public TemplateBackupModel(){
setPassword(new EntityModel());
AsyncQuery _asyncQuery = new AsyncQuery(); _asyncQuery.setModel(this); _asyncQuery.asyncCallback = new INewAsyncCallback() { @Override public void onSuccess(Object model, Object result) {
} };
}
@Override public void eventRaised(Event ev, Object sender, EventArgs args) { super.eventRaised(ev, sender, args); }
public boolean validate(){ return true; } } ========================================================
And created a model in the backup button click callback like this£º ======================================================== public void backup() {
if (getWindow() != null) { return; }
TemplateBackupModel model = new TemplateBackupModel(); setWindow(model); model.setTitle("TemplateBackup");//$NON-NLS-1$ model.setHashName("TemplateBackup");//$NON-NLS-1$
UICommand tempVar = new UICommand("OnBackup", this); //$NON-NLS-1$ tempVar.setTitle(ConstantsManager.getInstance().getConstants().ok()); tempVar.setIsDefault(true); model.getCommands().add(tempVar); UICommand tempVar2 = new UICommand("Cancel", this); //$NON-NLS-1$
tempVar2.setTitle(ConstantsManager.getInstance().getConstants().cancel()) ;
tempVar2.setIsCancel(true); model.getCommands().add(tempVar2);
} ========================================================
