I have a form with required input fields. The Form has an AjaxsubmitButton. Now
I want to mark each missing required field. How can I determine which field is
missing?
Unless each missing field is provieded, the Form's model object remains null.
My idea was to place a hidden FeedbackPanel on the Panel ofr Form. The feedback
Panel has a (protected) method "getCurrentMessges" which results in a List of
FeedbackMessages. Each FeedbackMessage has e mehtoc called "getReporter" that
gets the reporting component. So I could do something like
@Override
protected void onError(AjaxRequestTarget target, Form form) {
List<FeedbackMessge> list = feedbackPanel.getCurrentMessages();
for (FeedbackMessage message : list) {
if (message.getReporter == componentA) {
componentA.add(new AttributeModifier("class", true, new
Model<String>("requiredFormInput")));
target.addComponent(componentA);
}
But the getCurrentMessages method is protected and I have to declare my own
FeedbackPanel with an overwritten getCurrentMessagesmethod.
is there another mechanism to determine the Form comonents, that cause errors
(not only required fields)?
