                                          <h:outputText value="भेटीचे कारण" />
                                          <h:outputText value="#{per.reason}" />

                                          <h:outputText value="भेटीचे वेळ" />
                                          <h:outputText value="#{per.d}" />
                                      </p:panelGrid>
                                  </p:rowExpansion>
                            </p:dataTable>

并支持Bean，我想在其中显示新编辑的值......

public void onRowSelect(SelectEvent event)
     {

         System.out.println(event.getObject().toString());      
         DataTable objDataTable = (DataTable) event.getSource();
         System.out.println("Get Row Data : "+objDataTable.getRowData("id"));
         PersonBean pb=new PersonBean();
         pb=(PersonBean)objDataTable.getRowData();
         int id=pb.getId();
         String name=pb.getName();
         String address=pb.getAddress();
         String mobilenumber=pb.getMobilenumber();
         String reason=pb.getReason();


}

如果你想在数据库更新后从datata获取新值，你应该使用rowEdit事件。

<p:ajax event="rowEdit" listener="#{bean.listener}"/>

<p:column>
   <p:cellEditor>
      <f:facet name="output">
           <h:outputText value="#{per.name}"/>
       </f:facet>
       <f:facet name="input">
             <h:inputText value="#{per.name}" required="true"/>
        </f:facet>
   </p:cellEditor>
  </p:column>

 public void update(RowEditEvent event) {
   // use event.getObject() here
}

如何获取已编辑的数据表行的新值？
