Hi all , I want to to support multiple language in my application ,I didn't find a clear example in the vaadin book to in how to support internationalization and how to change between languages dynamically (I mean by just choosing another language from language bar and don't need to refresh or restart the application) .
For a more from-scratch implementation and a nice working example, see the GasDiary application and the source code in LoginScreen.java and GasDiaryApplication.java. It doesn't use i18n4vaadin, but rebuilds the UI after a language switch - it's a good enough solution for a login screen.
