With indexed properties, it's best to implement a 'validate' method on your action. Yes, it's a pain, but, before you file an improvement JIRA, I would suggest trying to come up with a patch. I know I, for one, have been patiently waiting on JSR-303 before I consider writing improvements to the validation framework. -Wes -- Wes Wannemacher Author - Struts 2 In Practice Includes coverage of Struts 2.1, Spring, JPA, JQuery, Sitemesh and more http://www.manning.com/wannemacher --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
