I went crazy and did this, I relied on I think Al Maw's thing from WUG
London :
Add the below visitor to your form, you can also easy do scriptacoulus
effects with this approach eg make the offender shake..
package zeuzgroup.application.component;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;
import org.apache.wicket.Component;
import org.apache.wicket.Component.IVisitor;
import org.apache.wicket.markup.html.form.FormComponent;
public class ShinyFormVisitor implements IVisitor, Serializable {
Set visited = new HashSet();
public Object component(Component c) {
if (!visited.contains(c)) {
visited.add(c);
if (FormComponent.class.isInstance(c)) {
c.setComponentBorder(new RequiredBorder());
c.add(new ValidationMsgBehavior());
c.add(new ErrorHighlightBehavior());
}
}
return IVisitor.CONTINUE_TRAVERSAL;
}
}
package zeuzgroup.application.component;
import org.apache.wicket.Component;
import org.apache.wicket.behavior.AbstractBehavior;
import org.apache.wicket.markup.ComponentTag;
import org.apache.wicket.markup.html.form.FormComponent;
public class ErrorHighlightBehavior extends AbstractBehavior {
public void onComponentTag(Component c, ComponentTag tag) {
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
tag.put("class", "error");
}
}
}
package zeuzgroup.application.component;
import org.apache.wicket.Component;
import org.apache.wicket.markup.html.border.MarkupComponentBorder;
import org.apache.wicket.markup.html.form.FormComponent;
public class RequiredBorder extends MarkupComponentBorder
{
public void renderAfter(Component component)
{
FormComponent fc = (FormComponent)component;
if (fc.isRequired())
{
super.renderAfter(component);
}
}
}
Required border
<html>
<body>
<wicket:border>
<wicket:body/>
<span class="requiredHint">*</span>
</wicket:border>
</body>
</html>

Thanks, Igor. I've been playing around with your suggestions but still doesn't
seem to make it work.
My onSubmit is not being called when I set a breakpoint there.
Is it possible that what I am asking for is not possible?

Thanks, Igor. However, I tried it and it never showed up in the browser.
Even more so, when I set a breakpoint to the onComponentTag-method, it never
gets called. Is that correct?
I only get this behavior when I am using the IndicatingAjaxButton--everything
works fine with the regular buttons. Maybe I am missing something else here...
Here's my code:
/**
* The panel with the form.
*/
public class SignInPanel extends Panel
{
public SignInPanel(final String id)
{
super(id);
feedback.setOutputMarkupId(true);
add(feedback);
add(new SignInForm("signInForm"));
}
public final class SignInForm extends StatelessForm
{
private final ValueMap properties = new ValueMap();
public SignInForm(final String id)
{
super(id);
FormComponent fc;
fc = new RequiredTextField("username", new PropertyModel(properties,
"username"));
fc.add(new InvalidIndicator());
fc.setOutputMarkupId(true);
add(fc);
fc = new PasswordTextField("password", new PropertyModel(properties,
"password"));
fc.add(new InvalidIndicator());
fc.setOutputMarkupId(true);
add(fc);
AjaxFormValidatingBehavior.addToAllFormComponents(this, "onsubmit");
this.add(new IndicatingAjaxButton("submit", this)
{
@Override
protected void onSubmit(AjaxRequestTarget target, Form form)
{
//perform sign in
}
@Override
protected void onError(AjaxRequestTarget target, Form form)
{
target.addComponent(feedback);
}
});
}
}
/**
* The validator. Thanks to Igor.
*/
public class InvalidIndicator extends AbstractBehavior
{
@Override
public void onComponentTag(final Component component, final ComponentTag tag)
{
boolean valid = ((FormComponent)component).isValid();
if(!valid)
{
tag.getAttributes().put("class","invalid");
}
}
}

I basically want to achieve this:
http://www.jroller.com/karthikg/entry/wicket_and_ajax
but handle the validation only after the form has been submitted with an
AjaxIndicatingButton instead of with the "onblur" as in the example.
I think I tried too many things over the last couple of days and got totally
confused now. Would anybody be so kind to help me out a bit? What do I need
to add to the FormComponents so that they will be updated with an
HTML-attribute "class='invalid'"? So far my form doesn't do that (I did
setOutputMarkupId(true)).
Thanks a ton!
