Struts2 - ScopedModelDriven - Unable to update the model in session

Question

Hi,
I have a problem implementing ScopedModelDriven.
I Have Model / User Java Bean object in action class.
I am trying to implement concept of same model object being used for 3 JSP pages with PREVIOUS and NEXT button navigation.Data to be updated in Model object for every page navigation and to be saved in session.
It is found the latest data is found from value stack when jsp page is navigated to next page, but not updated in Model object either in request or session scope I am sure I have configured necessary interceptors properly.
This could be easily done in struts1 by setting the Actionform in session scope.Any advice or thought?.

I am very surprised that you aren't aware of the CODE tags after being registered here for 5 years. Now your whole post with raw and unformatted code is hard to read. Make use of CODE tags to post code. You can use the CODE button in the toolbar of the message editor to get them.
With regard to your actual problem: as this is a Struts specific issue and you're here at a JSP forum, all I can do is to suggest you to use a forum/mailinglist devoted to Struts if you don't get sufficient support here after a while.
