You must override the onError method and add a
target.addComponent(feedback) :)

I cannot seem to get the Feedback panel to be displayed on a Form submit.
I have a custom form component that extends Form to which I'm adding an
AjaxSubmitButton using:
add(new AjaxSubmitButton("submit", this) {
private static final long serialVersionUID =
4557185412512174512L;
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
fromDate = (Date) fromDateField.getConvertedInput();
toDate = (Date) toDateField.getConvertedInput();
target.addComponent(nbrOfAuthenticationsChart);
target.addComponent(feedbackPanel);
}
});
The feedback panel is added using (it's located outside the form in another
component):
add(feedbackPanel = new FeedbackPanel("feedback"));
feedbackPanel.setOutputMarkupId(true);
I've also added an AjaxFormValidatingBehavior to the form:
AjaxFormValidatingBehavior.addToAllFormComponents(this, "onclick");
and I'm using a special form validator that extends AbstractFormValidator
that I've also added to the custom form.
The ajax submission works when I press the submit button but there are no
form errors displayed if there are any errors. The problem seem to be that
the feedback panel is never displayed and I cannot seem to figure out why.
I'm using Wicket 1.2.6. I've looked in the example at
http://www.wicket-library.com/wicket-examples/ajax?wicket:bookmarkablePage=:wicket.examples.ajax.builtin.FormPage
but that example doesn't seem to work at all.
Could anyone give me a clue?
