My first CRUD with vaadin and hibernate

Hi People:

After finding this wonderful tool that is vaadin , 3 days ago that I’m using , I could create my first crud with hibernate + this framework , so I am quite happy with this tool ,.

Now I would love to have people interested in reviewing my code and check if I’m using good or bad practices.
Excellent tool , totally recommended .

I leave screenshots in case anyone cares : S .

Excuse my bad English and I think it will create a video tutorial about this.
