Vaadin and Roo.

Hello.
I’m new to vaadin and I’m curious to try it.
I mainly develop web application.
My question is: what the advantage of using roo plugin?
Reading docs it seems to me that all can be done with vaadin, so why Roo?
Thank you.

no answers?

Please there is someone that can answer?

i haven’t used ROO for vaadin yet, but as nobody else has answered… the ROO for gwt was able to auto-generate a CRUD app source code for me. You just define the columns you want for your database tables and in 10 minutes you can get a CRUD web app running.
