Hi People Im using in my navigation rules to avoid the dreaded "Web page has expired" page. redirects render urls with the appropriate cid parameter and allow my users to move forward and backwards using IE buttons HERES AN EXAMPLE URL http://localhost/CRSWebApp/CRForNewDoc_part2.seam?cid=14&clr=true ...i have one problem and thats Validation. if a user submits a form with validation errors the lovely URL gets rewritten without the cid parameter..... which means when the user tries navigating back to this page all he/she gets is "Web Page has expired" Validation example <h:inputText size="70" id="Document_Title" value="#{newGsmsData.documentTitle}" required="true"> any ideas on how to retain the origional URL with the cid? As allways many thanks H View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100894#...
