p：手风琴更新标签标题

Question

我想问一个问题，有没有办法更新标签标题，尤其是在p：ajax event =＆＃34; tabClos​​e＆＃34;？ 因为当我尝试使用此ajax事件更新组件时，标题已更改但标签未关闭且组件卡住。 这是手风琴专家组的代码。

<p:accordionPanel id="searchEmployeeAccordionPanelId"                                       
                    widgetVar="searchEmployeeAccordionPanelId"                                      
                     dynamic="true"                                     
                      cache="true"                                     
                       activeIndex="#{Employee.accordionIndex}"                                     
                        style="margin-left: #{Employee.searchEmployeeDataTablePanelRendered ? '20%':''}">                                              
    <p:ajax event="tabChange"                                   
            listener="#{Employee.tabChangeSearchEmployeeAction}"                                
            update="@([id$=searchEmployeeAccordionPanelId])"                               
             global="false"/>                                               

     <p:ajax event="tabClose"                                  
            listener="#{Employee.tabCloseSearchEmployeeAction}"                                
            update="@([id$=searchEmployeeAccordionPanelId])"   />   

 <p:tab id="tabTitleId" title="#{Employee.showSearchPanelGridLink}" >                            
        <h:panelGrid id="searchEmployeePanelGridId"                                         
                     rendered="#{Employee.searchEmployeePanelGridRendered}">  
        </h:panelGrid>
 </p:tab>                    
 </p:accordionPanel>

以下是tabClos​​e ajax事件监听器的代码。

public String tabCloseSearchEmployeeAction(TabCloseEvent event)    {
String activeIndex = ((AccordionPanel) event.getComponent()).getActiveIndex();                     
 if (activeIndex.equalsIgnoreCase("0"))        
 {                    
 event.getTab().setTitle(showSearchLabel);               
 showSearchPanelGridLink = event.getTab().getTitle();        
 }       
 return null;    
 }

以下是tabChange ajax事件监听器的代码。

public String tabChangeSearchEmployeeAction(TabChangeEvent event)    {                
String activeIndex = ((AccordionPanel) event.getComponent()).getActiveIndex();                     
 if (activeIndex.equalsIgnoreCase("0"))        
 {                    
 event.getTab().setTitle(hideSearchLabel);               
 showSearchPanelGridLink = event.getTab().getTitle();        
 }       
 return null;    
 }
