input validation is declarative, meaning you simply tell Tapestry what

class="confluence-information-macro-body">
<p>Starting in Tapestry 5.4, the default behavior for server-side validation
failures is to re-render the page within the same request (rather than emitting
a redirect). This removes the need to use a session-persistent field to store
the validation tracker when validation failures occur.</p></div></div></div>As
with other action requests, the result of a form submission (except when using
<a shape="rect" href="ajax-and-zones.html">Zones</a>) is to send a redirect to
the client, which results in a second request (to re-render the page). The
ValidationTracker must be <a shape="rect"
href="persistent-page-data.html">persisted</a> (generally in the HttpSession)
across these two requests in order to prevent the loss of validation
information. Fortunately, the default ValidationTracker provided by the Form
component is persistent, so you don't normally have to worry about
it.<p>However, for the same reason, the individual fields updated by the
components should also be persisted across r
equests, and this is something you <strong>do</strong> need to do yourself
– generally with the @Persist annotation.</p><p>For example, a Login
page, which collects a user name and a password, might look like:</p><div
