p : p : dataTable의 commandButton

Question

p : dataTable 내의 p : commandButton에 문제가 있습니다. 내 버튼이 내 Backing Bean의 프로 시저를 호출하지 않습니다. 왜이 버튼이 작동하지 않는 사람이 있습니까?

버튼 코드 :

<p:column headerText="Details" style="width: 10px;"> 
          <p:outputPanel id="buttonDetail"> 
           <p:commandButton icon="ui-icon-vwfList" 
               styleClass="colButton" 
               action="#{customerChangeHistoryHandler.selectHistoryElement()}" 
               id="buttonDetail"           
               update=":historyDetail" 
               title="GO!!!"> 
           </p:commandButton> 
          </p:outputPanel> 
         </p:column>

데이터 모델 RequestScoped에 대해 Bean을 사용할 수있는 방법이 있습니까?

Answer 1

문제점을 발견했습니다. 첫 번째 데이터 테이블에 대한 데이터 모델을 제공하는 두 번째 빈이 있습니다. 이 빈은 RequestScoped 였고 ViewAccessScoped가 기본 백킹 빈이 아니 었습니다. 범위를 변경하고 버튼 호출이 작동 중입니다.
