I'm currently using this without any problem:
FormPanel form = FormPanel.wrap(Document.get().getElementById
("loginForm"));
form.addSubmitHandler(new FormPanel.SubmitHandler() {
public void onSubmit(FormPanel.SubmitEvent event) {
if (!validateForm()) {
event.cancel();
}
}
});
where validateForm() uses other Document.get().getElementById(...) to
check that the username and password fields are both filled.
