Please add this into MainTabTemplateView: ... getTable().addActionButton(new WebAdminButtonDefinition<VmTemplate>(constants.templateBackup()) { @Override protected UICommand resolveCommand() { return getMainModel().getTemplateBackupCommand(); } }); ... This adds a button under "Template" main tab. When clicked, it executes given command (getTemplateBackupCommand) on model (TemplateListModel). Model's executeCommand() ensures that backup() method is called. Inside backup() method, you call setWindow(model) which triggers an event - UI infra handles this event and uses "getModelPopup" (see TemplateModule) to resolve "window model" to GWTP PresenterWidget which is then revealed as popup. This is how dialogs work in UiCommon / UI (GWTP) infra. > how could I got the returnValue after executeCommand As I wrote above, executeCommand() just calls appropriate method (like backup) on the list model. That method has no return value (void) since it uses setWindow(model) to trigger event to notify UI infra to reveal a dialog. If you need to pass data to dialog, for example: ... TemplateBackupModel model = new TemplateBackupModel(); setWindow(model); ... set window model's title, help tag, hash name ... model.setSomeData(abc); model.doSomething(); ... In other words, after you call setWindow(model) you can modify state of window model (TemplateBackupModel) which can be reflected into UI (TemplateBackupPopupView) by use of editor widgets. As for binding window model's (TemplateBackupModel) attributes to UI (TemplateBackupPopupView) fields: // inside TemplateBackupModel private EntityModel<String> foo; public EntityModel<String> getFoo() { return foo; } public void setFoo(EntityModel<String> value) { foo = value; } // inside TemplateBackupPopupView @UiField @Path(value = "foo.entity") StringEntityModelTextBoxEditor fooEditor; Please see DataCenterPopupView.java & DataCenterPopupView.ui.xml (simple dialog view as example) for details.
