Another option would be to register cancel() as a dedicated action: http://struts.apache.org/docs/action-configuration.html#ActionConfiguration-ActionMethods Then you would need another (non-visible) form with an according action attribute. But as cancel should not change server state or involve Database operations I would rather use a link (styled as button) instead of submitting a form. That gives you just a GET request while a form submit usually means a POST-Redirect-GET cycle. Regards, Christoph This Email was scanned by Sophos Anti Virus
