Examples of com.vaadin.navigator.Navigator.addView()

com.vaadin.navigator.Navigator.addView()
Registers a static, pre-initialized view instance for a view name.
Registering another view with a name that is already registered overwrites the old registration of the same type.
Note that a view should not be shared between UIs (for instance, it should not be a static field in a UI subclass). @param viewName String that identifies a view (not null nor empty string) @param view {@link View} instance (not null)

        ViewDisplay display = new Navigator.ComponentContainerViewDisplay(
                container);
        Navigator navigator = createNavigator(new NullFragmentManager(),
                display);


        navigator.addView("tv1", tv1);
        navigator.addView("tv2", tv2);


        navigator.navigateTo("tv1");


        assertSame(tv1, container.getComponent(0));
