등록 후 체크 박스를 바인딩 할 수 없습니다 나는 팀 등록하는 다음과 같은 일련의 단계했습니다 :심지어 사용자 정의 속성 편집기
- 선택 팀 -이 체크 박스 등이 팀의 플레이어의 목록이 표시됩니다에게 (JSP 페이지 하단)
- 표시 할 플레이어를 하나 이상 선택할 수 있습니다.
newdTeam요청 처리 방법은 위의 2 단계에서 선택한 플레이어를 설정해야합니다. 처리기가 호출되고 있지만 2 단계에서 플레이어를 선택한 경우에도players세트가 비어 있습니다. 문제가 어디에 있는지 알 수 없습니다.
속성 편집기가 호출되지 않습니다. 어떤 도움을 주셔서 감사합니다.

따라서 playe 내가 볼 rPropertyEditor
