Question

当我在标准页面中使用primefaces文件上传时，一切正常。但是当在包含的页面中添加它时，fileupload事件永远不会调用

在树节点单击上加载的动态包含页面如下

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui"
    >
    <h:form id="upForm" target="_blank" >   

        <p:fileUpload fileUploadListener="#{fileUp.handleFileUpload}" 
                      mode="advanced"
                      update="messagesup"
                      multiple="true"

                      sizeLimit="20971520"
                      label="Select File"
                      allowTypes="/(\.|\/)(gif|jpe?g|png|pdf|doc?x)$/"/>
        <p:growl id="messagesup" showDetail="true"/>  



    </h:form>
</ui:composition>

PrimeFaces的FileUpload在动态加载的页面内不起作用
