명령 단추 요금 빈 값

Question

나는 jsf2.2 primefaces 6.0을 사용하고있다. 나는 테이블의 클릭에 대한 요구 사항 던지기의 세부 사항을 보여주는 클릭 가능한 인터페이스를 만든다. 그 후, 나는 2 개의 특정 조건에 표시된 명령 단추를 만든다. (수요가 "Encours"또는 "Amodifier"일 때만). 내 문제는 수요 세부 정보를로드하려고 할 때 "수정 자"버튼을 누르면 빈 값이 청구됩니다. 이전에 테이블을 클릭 할 때만 전 값을로드합니다. 수요에 대한 세부 정보를 표시합니다. 그 후에 데이터를 업데이트하기 위해 "수정 자"버튼이 필요하기 때문에이 문제를 해결하는 데 도움이 필요합니다.

Answer 1

나는 우선 내가 당신의 버튼 대신 onclick="PF('d3').show();" 의 oncomplete="PF('d3').show();"이 있어야합니다 생각하고 있어야합니다, 바로 문제를 이해했다면 속성 update="d3" 여기에서 d3은 올바른 대화 위젯 ID입니다. 어떻게 작동하는지 설명해 보겠습니다. 먼저 버튼을 클릭하십시오.이 버튼은 javaBean의 속성을 업데이트 한 후 대화 상자를 백엔드의 새로운 변경 사항으로 업데이트합니다. 마지막으로 요청이 끝나면 대화 상자가 열립니다.
