You end up with methods like onValidateFormFromLogin() which is just asking for trouble.
onFormValidateFromLogin() is a bit better.
Obviously, we keep the old name as well ... have to fire two events at the validate form stage.
What would be a better name? Something that doesn't have "form" is it; perhaps "finalValidation" or just "validate". I remember this was a problem with calling it "validate" before, because this conflicted with the validate event form form control element components ... but is that really a problem?
