for the versioning to work properly though you need to remember changes done against your dataprovider because it keeps its own state that needs to be rolled back. attached is the submitlinkpage.java that shows you how to do that.

yeah i can reproduce it to, the problem is that the submitlink changes the form's value using _javascript_ - and the browser remembers it in its cache! so when you go back that cahnged url is present. ugly, im going to look for a solution.

Because in the traffic ammount of the mailing list it can be forgotton..

Can you confirm that you see the problem too and that it is indeed a
