I think it is perhaps a JBoss error. Because the parameters in ServletRequest should be immutable, that means Struts (or other frameworks) has no chance to change the Request parameters. See: http://download.oracle.com/javaee/5/api/javax/servlet/ServletRequest.html#getParameterMap%28%29
So the parameters maybe duplicated BEFORE struts get involved Suggest you to check your JBoss or web app configuration. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
