Question

我正在使用PrimeFaces 3.5和OmniFaces 1.5。在我的主页上，我有一个民意调查组件来刷新一些内容。另外，我正在使用FullAjaxExceptionHandler在ajax请求期间出现异常时显示错误页面。

index.xhtml

<h:form id="formBsvtt">
  <p:messages autoUpdate="true" showDetail="false" />
  <p:outputPanel id="panelOut" layout="block">
    ...
    ... content to refresh
    ...
  </p:outputPanel>
  <p:panelGrid id="panelIn" layout="block">
    ...
    ... various interaction with user and database access
    ...
    <ui:include src="page1.xhtml" />
    <ui:include src="page2.xhtml" />
    <ui:include src="page3.xhtml" />
    ...
  </p:panelGrid>
  <p:poll widgetVar="poll1" autoStart="true" global="false" interval="15" 
    partialSubmit="true" process="@this" update="panelOut"
    listener="#{myBean.myListener}">
  </p:poll>
</h:form>

web.xml

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/errorViewExpired.xhtml</location>
</error-page>
<error-page>
    <exception-type>java.sql.SQLException</exception-type>
    <location>/errorSQL.xhtml</location>
</error-page>
<error-page>
    <exception-type>java.lang.RuntimeException</exception-type>
    <location>/errorRuntime.xhtml</location>
</error-page>

我的问题是：如果出现异常，将显示指定的错误页面，但不会停止轮询，然后每隔15秒显示一次ViewExpired错误页面。我试图用

来阻止它

<h:outputScript>poll1.stop();</h:outputScript>

在错误页面上，但这不起作用。

如果出现异常，如何停止投票？

更新我不使用模板。这是我的错误页面：

        <h:outputScript rendered="#{facesContext.partialViewContext.ajaxRequest}">scrollTo(0, 0);</h:outputScript>

    </h:body>

如何在调用OmniFaces“FullAjaxExceptionHandler”后阻止PrimeFaces轮询连续轮询
