Subject: Struts2 - ScopedModelDriven - Unable to update the model and set
the latest Model data in session
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?.
