changing myiu content from loginapp.class

Hi all,
I am new at vaadin, with little java knowledge,

doing test app with login screen,

in myui
 i have this, 

 if (CurrentUser.isLoggedIn()) {
            setContent(new FullApp());
        } else {
            setContent(new LoginApp());
        }

LoginApp loads and and auth user from shiro, everything works,

but i dont know to to set content  at myui after auth in LoginApp class,
so i did this,

        if (CurrentUser.isLoggedIn()) {
            setContent(new FullApp());
        } else {
            setContent(new LoginApp((UI)this));
        }

and in loginapp

after auth
UI.setcontent(new FullAapp());

This works well too,
But i didnt feel comfortable with this code,
Is this good way of doing this or is there any proper way of doing,

Thanks for you replies,

Hi,

this sounds like a typical use case for the built-in Navigator. Take a look at the Book of Vaadin for more info: https://vaadin.com/docs/-/part/framework/advanced/advanced-navigator.html

HTH,
