I guess a better explanation is due. Ok the user sees /viewUser.do?id=4 which in my action pulls the User object with ID 4 from the db, places it in to the request, then loads the .viewUser tiles definition and displays the data. In that page is a form that submits to /addEmailAddress.do. If the xml validation fails on submitting it then pulls the input forward from addEmailAddress.do, which I tried setting to input=".viewUser", the tiles definition. After a failure validating, my jsp reports an error finding the user object, because when you submit you are getting a new request, and the user object is no longer loaded into the request object. I also tried setting the input element to be input="/viewUser.do", which runs the action again, but doesn't have the id=4 parameter I need to specify which user object to load out of the database. Make sense? So essentially what I am looking for is a way to modify the input forward that is used when validation fails. I tried this in the validate method of my form, however it says configuration locked if I do a setInput(), and if I do getInputForward then modify it, it doesn't seem to do anything.. (probably returning a copy). So.. if anyone has any ideas.. :) Thanks, David --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
