You can listen for the validation events on the individual form elements of
your component.
eg:
@Enviromental
private ValidationTracker validationTracker;
@OnEvent(component = myFormField, value = EventConstants.VALIDATE)
private void validateFormField(Object valueAboutToBeSet) {
//do your validation and record errors where needed with the
validationTracker
}
Hope this helps,

I have a component which is a wrapper around some form fields. (Imagine

If I want to provide some custom validation, is there a way to listen to
the
enclosing form's validation event? The problem is that the form is
defined
in the page, not in my component. Right now, the page catches the
validation
event and then calls a validate(Form form) method on my component.
But I'm wondering if there's a way to have my component do this
automatically, so that future users won't have to remember to hook this
up.
(Plus, the page's validation event handler does nothing else, so it's
kinda
silly.)
Any tips greatly appreciated!
