Yes, as Rene said, a key concept behind WebWork/Action2 is the "value stack". The value stack works something like the page/request/session/application scopes. If you push something on to the stack, and someone asks for a property by that name, what was pushed on last is returned first. In the case of validation, essentially, the string property we want to redisplay is pushed onto the stack, so the tags find it there first. -Ted. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
