< 원인 >

form이 있지만 form을 사용하지 않고 onClick으로 값을 전달하여 댓글 컨트롤러로는 값이 가지만 NoticeContorller에는 값이 가지 않아 boardSeq와 boardTypeSeq가 없을 시 나오는 에러 메시지인 " boardSeq와 boardTypeSeq가 필요합니다. "가 나옴

< 해결 >

원인을 정확하게 나오지 않아 몇일동안 고생을.....

분명 댓글 작성 Controller에서는 boardSeq와 boardTypeSeq값이 나오는데 댓글작성 후 페이지 새로고침시 사용하는 NoticeController에서는 값이 없다고 나와서 댓글이 DB에 제대로 작성이 되어 다시 가보면 있지만 새로고침시 에러가 계속 발생하였음......

진짜 찾기 어려운 에러였다.....

다신 보지 말자...
