<p:ajax> 내부 사용 방법 <p:tree> primefaces?

<p:tree>을 사용하고 있습니다. <p:ajax>을 사용하여 선택된 노드를 감지하고 조치를 취하려고합니다.<p:ajax> 내부 사용 방법 <p:tree> primefaces?

<p:tree id="treeDot" value="#{beanRequest.rootDot}" var="node" selectionMode="single" 
    nodeSelectListener="#{beanRequest.clt}" > 
    <p:ajax event="select" listener="#{beanRequest.clientSelected}" /> 
     <p:treeNode> 
      <h:outputText value="#{node}" /> 
     </p:treeNode> 
</p:tree>

서버 측 방법 :

//... 
private Client clt; 
public void clientSelected(NodeSelectEvent event) { 
    //... 
} 
//...

나는 다음과 같은 예외를 얻을 :

내가 실수를 발견이 내 실제 JSF 코드입니다. 단지 selection="#{beanRequest.selectedNode}" 에 의해 nodeSelectListener="#{beanRequest.clt}"를 교체하고 사용 된 Primefaces이 private TreeNode selectedNode;

어떤 버전의 같은 beanRequest에서 selecttedNode 변수를 생성? – Ghasfarost
