How to create a mandatory start screen in Cuba ?
i.e. The screen will be having some input fields and it should not show any menu items at the start ,
once the user enters values after validation it should show other screens in menu.

Hello @Vignesh_Iyer

You should create an extension of com.haulmont.cuba.web.DefaultApp class and replace default implementation in the web-spring.xml file:

<bean name="cuba_App" class="com.company.sample.web.MyApp" scope="vaadin"/>

Then override String routeTopLevelWindowId() method to return your mandatory screen id. And just show default main screen when user passes validation:

// in App extension

removeAllWindows();

AppUI ui = AppUI.getCurrent();
Screens screens = ui.getScreens();

Screen screen = screens.create("mainWindow", OpenMode.ROOT);
screens.show(screen);

Hi Daniil Tsaryov,
I am working on 6.10 version and not able to access the removeallWindows() method

Okay, for 6.10 version an implementation will be the following:

// in mandatory screen

@Inject
protected TextField secret;
@Inject
protected WindowConfig windowConfig;

public void checkInput() {
    if (!"top secret".equals(secret.getValue())) {
        showNotification("Wrong", NotificationType.WARNING);
        return;
    }

    App.getInstance().closeAllWindows();

    ((WebWindowManager) getWindowManager())
            .createTopLevelWindow(windowConfig.getWindowInfo("mainWindow"));
}
