Like I've tweeted a few days ago, I've implemented a BigTableGAEPageStore for Wicket so we can advance another step further full compatibility with Google App Engine.
The project can be seen at http://code.google.com/p/gawcket It is a fork of wicket-gae-template with a modified Guestbook to not use LoadableDetachableModel and the BigTableGAEPageStore. With this said, you can go to http://gawcket.appspot.com and test it. Submit the form a few times and then modify the URL to reference an older version. You can check this video on YouTube to see how data is being stored at GAE's Datastore: http://youtu.be/ObvA9ao8U2Q I just hope I've done everything correctly on this implementation. So I ask the experts to take a look, and more important: to try it on your apps that run on more than one CPU at GAE. Thank you, Long live Wicket!!
