jsf2 primefaces.js錯誤$ browser.msie爲空或不是對象

Question

我有一個primafaces selectOneMenu。當我點擊渲染菜單時，下拉列表不會出現，瀏覽器出現此錯誤。我正在使用IE 8和primefaces 5.但是，當我更改爲h：selectOneMenu下拉菜單正常工作。請幫助，我卡住了。這裏是我的代碼：

 <p:selectOneMenu id="app" value="#{refbean.selapp}" rendered="#{refbean.selItem =='SMS NOTIFICATION'}"> 
       <f:selectItem itemValue="Select" itemLabel="Select Application"></f:selectItem> 
       <f:selectItems value="#{refbean.appList}"></f:selectItems> 
       <f:ajax event="change" 
         execute="@this" 
         render="shownotif" 
         listener="#{refbean.setNotificationValues}"> 
       </f:ajax> 
      </p:selectOneMenu> 

I also tried using <script src="http://code.jquery.com/jquery-migrate-1.1.1.js"></script> but the issue still remains. 



I am not able to test the ajax call because the drop down menu is not populated at all in the first place. When I click on the drop down menu i see the javascript error in the browser : `$browser.msie is null or not an object.` Here is my full code : 



<p:panelGrid id="showOption"> 
     <p:row id="showsms" rendered="#{refbean.selItem =='SMS NOTIFICATION'}"> 
     <p:column> 
     <p:outputLabel value="#{msg['createcr.app']}" rendered="#{refbean.selItem =='SMS NOTIFICATION'}" styleClass="LabelDescription"></p:outputLabel> 
     </p:column> 
     <p:column> 
     <p:selectOneMenu id="app" value="#{refbean.selapp}" rendered="#{refbean.selItem =='SMS NOTIFICATION'}"> 
      <f:selectItem itemValue="Select" itemLabel="Select Application"></f:selectItem> 
      <f:selectItems value="#{refbean.appList}"></f:selectItems> 
      <f:ajax event="change" 
        execute="@this" 
        render="shownotif" 
        listener="#{refbean.setNotificationValues}"> 
      </f:ajax> 
     </p:selectOneMenu> 
     </p:column> 
     </p:row> 

     <p:row id="shownotif" rendered="#{refbean.selItem == 'SMS NOTIFICATION'}"> 
     <p:column> 
      <p:outputLabel value="#{msg['createcr.notif']}" styleClass="LabelDescription"></p:outputLabel> 
      </p:column> 
      <p:column> 
     <p:selectOneMenu id="notif" value="#{refbean.selnot}" rendered="#{refbean.selItem == 'SMS NOTIFICATION'}"> 
      <f:selectItem itemValue="Select" itemLabel="Select Notification List"></f:selectItem> 
      <f:selectItems value="#{refbean.noList}"></f:selectItems> 
      <f:ajax event="change" 
        execute="@this" 
        render="showtext" 
        listener="#{refbean.setSelNotification}"></f:ajax> 
     </p:selectOneMenu> 
     </p:column> 
     </p:row> 
</p:panelGrid>

嘗試使用jquery-browser-plugin，將jquery.browser.min.js，包括它在你的webapp

一個jQuery插件瀏覽器檢測。 jQuery刪除了對1.9.1瀏覽器檢測的支持，所以它被抽象爲一個jQuery插件
