I've never had to populate an ActionForm to use it on a standard JSP page. It will simply use the default values of the ActionForm properties that you have for your ActionForm fields (if you don't declare any). (Strings are null, etc). With your procedure you are forced to call a populate method in oder to set up at least one HashMap with all the default values. -- Rick Reumann _______________________________________________ MVC-Programmers mailing list [EMAIL PROTECTED] http://www.basebeans.net:8080/mailman/listinfo/mvc-programmers
