Thanks Paul, Putting Bean in scope and manually calling validate worked for me. Appreciate your help.
Thanks Prakash -----Original Message----- From: Paul Benedict [mailto:[EMAIL PROTECTED] On Behalf Of Paul Benedict Sent: Sunday, December 03, 2006 2:12 PM To: Struts Users Mailing List Subject: Re: Problem with re displaying optionsCollection If you put the list in request scope, it disappears when the request is finished. That's why you're probably getting the error: the second request (failed validation) is trying to re-display the collection, but it no longer exists. You should either (1) put the list in sesssion scope or (2) turn off automatic validation, and put the list back into request scope before calling form.valdiate() Paul Prakash Inuganti -X (pinugant - Digital-X, Inc. at Cisco) wrote: > Hi, > > I am having an issue with select list and not able to figure out a > resolution.
