Apache Wicket에 관한 질문 : 여러 텍스트 입력 필드가있는 양식이 있습니다. 그것은 DateTextField를 추가 할 때까지 제대로 작동합니다. 오버라이드 된 onSubmit() 메소드는 단순히 더 이상 호출되지 않습니다. Wicket 예제를 살펴 봤지만 내 코드와 큰 차이는 볼 수 없습니다.DateTimeField가있을 때 양식의 onSubmit 메서드가 호출되지 않는 이유는 무엇입니까?

내가 브라우저에서 렌더링되는 HTML을 살펴했다
다음은 HTML 코드입니다. dateTextField가 존재하지 않는다면, 그것은 다음과 같습니다

</html>을 즉시 dateTextField이 존재하는 한, 형태는 자바 스크립트 호출에 추가 부서가 있습니다. 추가 부서가 모두 떨어져 갑자기 왜

</html>는 꽤 이해가 안 돼요. 내 생각 엔 자바 스크립트 호출이 작동하지 않는다는 것이다.
감사합니다.
