The following code seems to work fine on all of the browsers I have tried, except for Firefox 3.6.x.

What happens is that on each key up of invalid email address I get a duplicate error message appearing. This means that the error messages soon expand down the page.

Have I missed something or is it just a bug in Wicket or Firefox 3.6? (this is with Wicket 1.4.x - I just upgraded to 1.4.18 in the hopes that it was fixed there, I also tried some older versions of 1.4.x as well, and the latest 5.1 RC).

public class HomePage extends WebPage 
{
    private static final long serialVersionUID = 1L;

    public HomePage(final PageParameters parameters)
    {
        add(new FormX());
    }

    private class FormX
        extends Form<Void>
    {
        FormX()
        {
            super("form");
            final TextField<String>      field;
            final ComponentFeedbackPanel feedback;

            field = new TextField<String>("a");
            field.add(RfcCompliantEmailAddressValidator.getInstance());
            field.setRequired(true);
            field.setOutputMarkupId(true);
            feedback = new ComponentFeedbackPanel("b", field);

            feedback.setOutputMarkupId(true);
            add(field);
            add(feedback);
            AjaxFormValidatingBehavior.addToAllFormComponents(this,
                                                              "onkeyup",
                                                              Duration.milliseconds(250));
        }
    }
}

Turns out you need to use <span wicket:id="b"></span> instead of label.
