Places navigation proglem

[Arthur Rosenzahl]

Hi all,

we have a strange problem in a GWT/GWTP-Project. We have a couple of presenters and the navigation was totally fine. But now i tried to create a new one and it is impossible to go to this presenter. It always jumps to the default presenter.

All presenters are declared the same way in the application module:

public class ApplicationModule extends AbstractPresenterModule {

    @Override

    protected void configure() {

        install(new UiModule());

        // Application Presenters

        bindPresenter(ApplicationPresenter.class, ApplicationPresenter.MyView.class, ApplicationView.class,

                      ApplicationPresenter.MyProxy.class);

        bindPresenter(HomePresenter.class, HomePresenter.MyView.class, HomeView.class, HomePresenter.MyProxy.class);

        bindPresenter(DevicesPresenter.class, DevicesPresenter.MyView.class, DevicesView.class, DevicesPresenter.MyProxy.class);

        bindPresenter(ContainerListPresenter.class, ContainerListPresenter.MyView.class, ContainerListView.class, ContainerListPresenter.MyProxy.class);

        bindSingletonPresenterWidget(DeviceEditorDialogPresenterWidget.class, DeviceEditorDialogPresenterWidget.MyView.class,

        DeviceEditorDialogView.class);

        bindSingletonPresenterWidget(ContainerInfoPresenter.class, ContainerInfoPresenter.MyView.class,

        ContainerInfoView.class);

        bindSingletonPresenterWidget(SettingsPresenter.class, SettingsPresenter.MyView.class,

                SettingsView.class);

    }

}

 And our top level presenter is declared as follows:

public class ApplicationPresenter

        extends Presenter<ApplicationPresenter.MyView, ApplicationPresenter.MyProxy> 

        implements CurrentUserChangedHandler, AsyncCallStartHandler, AsyncCallFailHandler, AsyncCallSucceedHandler {

    /**

     * {@link ApplicationPresenter}'s proxy.

     */

    @ProxyStandard

    public interface MyProxy extends Proxy<ApplicationPresenter> {

    }

    /**

     * {@link ApplicationPresenter}'s view.

     */

    public interface MyView extends View {

        void setTopMessage(String string);

    }

    

    @ContentSlot

    public static final Type<RevealContentHandler<?>> SLOT_SetMainContent = new Type<>();

    @Inject

    ApplicationPresenter(EventBus eventBus,

                         MyView view,

                         MyProxy proxy) {

        super(eventBus, view, proxy, RevealType.Root);

    }

    @ProxyEvent

    @Override

    public void onCurrentUserChanged(CurrentUserChangedEvent event) {

    }

    @ProxyEvent

    @Override

    public void onAsyncCallStart(AsyncCallStartEvent event) {

        getView().setTopMessage("Loading...");

    }

    @ProxyEvent

    @Override

    public void onAsyncCallFail(AsyncCallFailEvent event) {

        getView().setTopMessage("Oops, something went wrong...");

    }

    @ProxyEvent

    @Override

    public void onAsyncCallSucceed(AsyncCallSucceedEvent event) {

        getView().setTopMessage(null);

    }

    @Override

    protected void onReveal() {

        // Workaround to set a body background in login page

        ScriptInjector.fromString("document.body.classList.remove('signin');")

                .setWindow(ScriptInjector.TOP_WINDOW).inject();

        

        // Inject the js that must be executed when the document is ready,

        // after gwt code is deployed, js for the template

        ScriptInjector.fromString(JsClientBundle.INSTANCE.docuReadyJS().getText()).setWindow(ScriptInjector.TOP_WINDOW).inject();

    }

}

The NameTokens are defined all the same:

public class NameTokens {

    public static final String homePage = "!homePage";

    public static final String loginPage = "!loginPage";

public static final String containersPage = "!containersPage";

//TODO why do we have two devices things?

    public static final String devicesPage = "!devicesPage";

    public static final String devicesDialog = "!devicesDialog";    

    public static final String uiExamplesPage = "!uiExamples";

    public static final String settingsPage = "!settingsPage";

    public static String getHomePage() {

        return homePage;

    }

    

    public static String getSettingsPage() {

        return settingsPage;

    }

    

    public static String getDevicesPage() {

        return devicesPage;

    }

    

    public static String getDevicesDialog() {

        return devicesDialog;

    }

    

    public static String getContainersPage() {

        return containersPage;

    }

    public static String getUiExamplesPage() {

        return uiExamplesPage;

    }

}

The presenter itself is just copied and renamed from an existing, working presenter:

public class SettingsPresenter extends Presenter<SettingsPresenter.MyView, SettingsPresenter.MyProxy>

        implements SettingsUiHandlers {

Logger logger = Logger.getLogger("RootLogger");

    /**

     * {@link SettingsPresenter}'s proxy.

     */

@ProxyCodeSplit

    @NameToken(NameTokens.settingsPage)

    // The first tab in the main page

    public interface MyProxy extends ProxyPlace<SettingsPresenter> {

    }

    /**

     * {@link SettingsPresenter}'s view.

     */

    public interface MyView extends View, HasUiHandlers<SettingsUiHandlers> {

    void setTitle(String title);

    }

    private DispatchAsync dispatcher;

    @Inject

    SettingsPresenter(final EventBus eventBus,

                      final MyView view,

                      final MyProxy proxy,

                      final DispatchAsync dispatcher) {

        super(eventBus, view, proxy, ApplicationPresenter.SLOT_SetMainContent);

        this.dispatcher = dispatcher;

        view.setUiHandlers(this);

    }

    

    @Override

    protected void onReveal() {

        getView().setTitle("Trust|me MDM");

    }

    

    @Override 

    protected void onReset() {

    super.onReset();

   

    }

Can the ClientModule definition be related to this?

public class ClientModule extends AbstractPresenterModule {

    @Override

    protected void configure() {

        install(new DefaultModule(DefaultPlaceManager.class));

        install(new ApplicationModule());

        install(new RpcDispatchAsyncModule()); // binds DispatchAsync to RpcDispatchAsync

        bind(ClientModelProvider.class).in(Singleton.class);

        bind(CurrentUser.class).in(Singleton.class);

        bind(IsAdminGatekeeper.class).in(Singleton.class);

        bind(LoggedInGatekeeper.class).in(Singleton.class);

        // DefaultPlaceManager Constants

        bindConstant().annotatedWith(DefaultPlace.class).to(NameTokens.homePage);

        bindConstant().annotatedWith(ErrorPlace.class).to(NameTokens.homePage);

        bindConstant().annotatedWith(UnauthorizedPlace.class).to(NameTokens.loginPage);

        // CSRF-Protection

        bindConstant().annotatedWith(SecurityCookie.class).to(ConstantHelper.securityCookie);

        

        // Load and inject CSS resources

        bind(ResourceLoader.class).asEagerSingleton();

    }

}

Sorry for posting so much and having such an unspecific question, but i really do not know how why the navigation just stopped working for new presenters.

Thanks for your help!

Can you post the module where the SettingsPresenter is bound

Sorry I see you did as the first file.

You're not binding the Settings Proxy,  copy the binding for another Presenter rather than Presenter Widget

[Arthur Rosenzahl]

Ahhhh i see.

Now it works! Thanks for your help :) I guess i got blind from looking too long at the code.
