How to show a bottom-of-the-page feedback panel?

If I have a feedback panel positioned together with a form at the bottom of
a very long page, how can I cause the browser to snap to that feedback panel
upon validation error?

I could use an anchor tag at the feedback panel, but how would I tell Wicket
to go to that anchor upon validation error?

Thanks,
Nate Roe

public class YourPage extends WebPage implement IHeadContributor {

........

    // in case form has error, scroll down
    @Override public void renderHead(IHeaderResponse r) {
        if (form.hasError()) {
            r.renderOnLoadJavascript("location.hash='YOUR-ANCHOR'");
        }
    }

}
