  • There’s no main window in Vaadin 7. But you have to set a (usually layout) component as the UI content with setContent()
  • addListener(ClickListener) → addClickListener
  • Your mainLayout is apparently an AbsoluteLayout. It still works like that.
  • Easiest: Notification.show() or new Notification(…).show(), etc.
