For more than a week I've a lot of time to work on Wicket-Dojo-Contrib, so now there are a lot of cool new features such as Calendar or lot of new container. Take a look at it on my web live demo.
No distrib is avalaible for the moment because I work on trunk (future wicket 2.0) some features are backported on 1.3 branch wich will be compatible with future wicket 1.3. So be patient, I will try to make a new distribution as soon as wicket 1.3 will come out.
