ADF 얼굴이 새로운데 af : selectOneChoice의 값 변경에 partialTrigger a : panelAccordion 문제가 있습니다. af : panelAccordion에는 af : showDetailItem 내에 여러 개의 af : showDetailHeader가 있습니다. 모든 af : showDetailItem 및 af : showDetailHeader가 동적으로 생성됩니다. 빈 대학 뷰 범위에 그 코드는 아래와 같습니다 : 부서 및 직원 클래스는 간단한 POJO이다af : panelAccordion partialtrigger on af : selectOneChoice valueChangeListener

. Department 클래스는 두 개의 필드, 즉 을 포함합니다. 1. departmentName 문자열과 2. 직원 클래스 도 해당 접근 자로 나열하고 Employee 클래스는 의 두 필드를 포함합니다. 1. 문자열 이름 및 2. 문자열 정보. selectOneChoice 다음 AF의 선택된 값에 따라 showDetailItem : 내가하고 싶은 것은 AF를 다시 정렬하는 것입니다

페이지의하여 jspx 코드
은 아래와 같습니다.나는 이미지에 문제를 보여주는 오전 : 
첫 번째 이미지는 페이지로드 후 정상 상태입니다 볼 수 있듯이. 부서 1에는 직원이 1 명뿐입니다. 직원 1과 부서 4에는 직원 1, 직원 2의 직원 2 명이 있습니다. 드롭 다운에서 부서 4를 선택한 후 부서 3은 마지막 위치에 있지만 부서 3 패널에는 분명히 두 개의 af : showDetailItem이 있습니다 원래는 한 명의 직원 만 있습니다. 또한 해당 추가 af : showDetailItem 클릭 할 수 없습니다.
아무도 나에게 매우 도움이 될 제안을 해주십시오.
감사합니다.
