변수를 초기화하고 HTML의 텍스트 필드와 결합하려고합니다. 함수를 호출 할 때이 변수를 사용하여 데이터베이스에 무언가를 삽입하려고합니다. 하지만 현재 필드에 null 값이 계속 표시됩니다. 어떤 아이디어?올바른 변수 초기화 방법 seam

여기서 bean 클래스의 refNumber는 무엇입니까 ?? 또는 표시되지 않는 오류? 예. doAction null로 해결 ... –
그냥 문자열을 사용할 수 있습니까? – David
xNhtml에서 myNumber로 refNumber를 변경하거나 bean 클래스에서 refNumber로 myNumber를 변경하십시오. –
