Subject Re: form-bean and persistent data in session scope

Hi Raghuveer,
You will have to clean up the session yourself.
Generally an application will have some type of menu (links). If you follow a naming convention
for the mappings for the  menu items (mapping seperate than that for the action), you can
check for that and clean up the session. This could be done in either a base action or by
extending the request processor.
