There is an example in howards book. The code is something like:
private void error(IValidationDelegate delegate, String componentId,
String message, ValidationConstraint constraint) {
IFormComponent component = (IFormComponent)
getComponent(componentId);
delegate.setFormComponent(component);
delegate.record(message, constraint);
}

My question is, say I have a select list in which the selected option
is "Choose One". The user forgot to choose one from the list so I
need to send an error back to the page and still maintain everything
in the form, like how a validator works. I also have the same case
when two fields do not match. How would I go about doing this?
Thanks.
