First, wrong list. [email protected] is where you'd want to ask those kind of questions. It covers Tapestry usage questions. This one here is for Tapestry development topics. Second, Nabble has that nice button called "subscribe" when a subscriptions is needed. Use it. It saves us time that we can than spend to answer your questions. Third, <t:errors /> displays server-side validation errors. Since client-side validation prevents you from submitting the form in the first place, no server side validation occurs and no errors are being displayed by the <t:errors /> component. Try disabling javascript in your browser and you will see that it works. Also see [1].
