Everything below here was added by aakoch, a novice, so please, if there is something wrong, fix it! Thanks!

Note

The above code won't compile under 1.3.0-BETA.

Here's some code that will work with version 1.3.0-BETA.

Code Block

protected void onError(final AjaxRequestTarget target, final Form form) {
    form.visitFormComponents(new IVisitor() {
        public Object formComponent(IFormVisitorParticipant formVisitor) {
            if (formVisitor instanceof FormComponent) {
                FormComponent formComponent = (FormComponent) formVisitor;
                
                if (!formComponent.isValid()){ 
                    // If this component failed validation, do something
                    // fancy to display it to the user...
                     target.addComponent(formComponent);
					 
                     // do a little dance
                     target.appendJavascript(
                        "new Effect.Shake($('" + formComponent.getMarkupId() + "'));");
                 }
            }
            return formVisitor;
        }
	});
}

To update the feedback panel:

Code Block

protected void onError(final AjaxRequestTarget target, final Form form) {
    // or update the feedback panel
    target.addComponent(form.getPage().get("feedback"));
}
