If I use the LoginOverlay I cant add new components to the screen?
I'm learning java and Vaadin, so I dont know many methods and how they work.

But if I want to create 3 login buttons for social media login, just the layout and nothing else, how I do using the LoginOverlay?

I did it using the VerticalLayout, but apparently using the VL I cant use the method addLoginListener. I really need to choose one? No way using both methods?

I have a problem:
Suddenly, while I was working on project I realized I can't run it. I mean, everytime I try to run (F6), it seems I make clean and build. I could do it before (I actually saw sometimes I had to clic run more than once or twice until it runs).
Does anybody knows what's the matter? I've been trying a lot of times without solve it.

If I want to add a new textfield using the login object, how do I do it?
