No it won't - what you specify in the validwhen "test" variable is an expression that if it results in "true" means validation passes - otherwise it fails. The condition you have means that the "comment" field will only be valid when ttype is 2 and comment is not null. So if ttype is not 2 or comment is not null validation will fail. To get it to work the way you want your expression should say "comment is valid when either ttype is not 2 OR comment is present" - that way when ttype is not 2 validation passes whatever tha value in comment, but when ttype is 2 then comment needs to be present. The reply I posted to your quesiton yesterday showed an expression to do exactly what you want (except it used 3 for ttype): http://www.mail-archive.com/user%40struts.apache.org/msg36235.html Niall --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
