What really happens when ActionForward= null is retuned from  execute() within a class extending  Action ?
Is this a supported/valid state within struts when no further mapping.findForward is desired ?
Thanks

Yes, ActionForward= null is valid retuned from  execute() . What happens in this case is that the view is NOT refreshed.
We used in our application for file download action when the UI view needs to remain same.
