我在primefaces的文件上传和对话方面遇到了很多问题。

我有一个按钮，当它被点击时会调用一个对话框。在这个对话框中，我有一个文件上传。当我选择一些文件并更新表单上的图像时，我希望此对话框关闭。这是代码：

<h:form id="formCadastroSistema">
  <div id="divCadastroComponenteConstrutivo">
    <h:outputText value="Cadastro de Componente Construtivo" style="font-size: 20px; color: black;"/>
    <p:layout style="height:240px; width: 100%; margin-top: 20px; padding-left: 40px;">
      <p:layoutUnit position="west" size="330" style="border: none;" resizable="false" >
        <p:graphicImage value="#{novoComponenteConstutivo.mostrarImagemDeByte()}" id="foto"/>
        <p:commandButton onclick="dialogUpLoad.show();" value="abrir"/>
      </p:layoutUnit>
      <p:layoutUnit position="center" style="font-size: 14px; border: none;">
        <h:panelGrid columns="2" cellspacing="5">
          <h:outputText value="Nome: "/>
          <p:inputText style="width: 295px;" value="#{novoComponenteConstutivo.novoComponenteConstrutivo.nome}"  />
          <h:outputText value="Categoria: "/>
          <p:selectOneMenu value="#{novoComponenteConstutivo.idCategoriaCamada}"  id="selectMenuCategoria" style="width: 305px;">
            <f:selectItems value="#{novoComponenteConstutivo.todasAsCategorias}" var="categoria" itemLabel="#{categoria.categoria}" itemValue="#{categoria.id}"/>
            <f:ajax event="valueChange" execute="selectMenuCategoria" listener="#{novoComponenteConstutivo.setarCategoriaDoNovoComponente()}" render="testi" />
          </p:selectOneMenu>
          <h:outputText value="Descrição: "/>
          <p:inputTextarea value="#{novoComponenteConstutivo.novoComponenteConstrutivo.descricao}" style="width: 295px; height: 50px;"/>
          <h:outputText value="Fabricante: "/>
          <p:selectOneMenu value="#{novoComponenteConstutivo.idFabricante}" id="selectMenuFabricante" style="width: 305px;">
            <f:selectItems value="#{novoComponenteConstutivo.todosOsFabricantes}" var="fabricante" itemLabel="#{fabricante.nome}" itemValue="#{fabricante.id}" />
            <f:ajax execute="selectMenuFabricante" event="valueChange" listener="#{novoComponenteConstutivo.setarFabricanteDoNovoComponente()}" render="testi2" />
          </p:selectOneMenu>

        </h:panelGrid>
        <h:outputText value="#{novoComponenteConstutivo.idCategoriaCamada}" id="testi"/>
        <h:outputText value="#{novoComponenteConstutivo.idFabricante}" id="testi2"/>
      </p:layoutUnit>
      <p:dialog style="height: 300px; width: 500px;" id="dialogUpLoad" widgetVar="dialogUpLoad" >
        <p:fileUpload fileUploadListener="#{novoComponenteConstutivo.uploadImagem}" update="foto" oncomplete="dialogUpLoad.hide();" multiple="false"  />
      </p:dialog>
    </p:layout>
    <p:separator/>
    <p:layout style="height: 150px; padding-left: 40px;" >
      <!--      -->
      <p:layoutUnit position="center" style="border: none;">
        <h:outputText value="Características Físicas" style="font-size: 18px;"/>
        <h:panelGrid columns="2" >
          <h:panelGrid columns="2" style="font-size: 14px; padding-top: 20px;" >
            <h:outputText value="Condutividade Térmica: "/>
            <p:inputText value="#{novoComponenteConstutivo.novoComponenteConstrutivo.condutividade}"  />
            <h:outputText value="Calor Específico: "/>
            <p:inputText value="#{novoComponenteConstutivo.novoComponenteConstrutivo.calorEspecifico}"/>
            <h:outputText value="Densidade Mínima: " />
            <p:inputText value="#{novoComponenteConstutivo.novoComponenteConstrutivo.densidadeMinima}"/>
          </h:panelGrid>
          <h:panelGrid columns="2"  style="font-size: 14px; padding-top: 20px; margin-left: 45px;" >
            <h:outputText value="Densidade Máxima: "/>
            <p:inputText  value="#{novoComponenteConstutivo.novoComponenteConstrutivo.densidadeMaxima}"/>
            <h:outputText value="Espessura: "/>
            <p:inputText value="#{novoComponenteConstutivo.novoComponenteConstrutivo.espessura}"/>
          </h:panelGrid></h:panelGrid>
        </p:layoutUnit>
      </p:layout>
      <h:commandLink value="confirm" style="position: absolute; right: 0px; font-size: 12px;" onclick="showDivConfirmacaoCadastroComponente();" >
        <f:ajax execute="@form" render=":formConfimacaoCadastroComponente" event="click"   />
      </h:commandLink>
    </div>
  </h:form>

它适用于 google chrome 和 FireFox，但 IE 对话框不会关闭并且图像不会更新。

可能是因为组件 ID 和 widgetVar 相同。

 id="dialogUpLoad" widgetVar="dialogUpLoad"

请同时参考这个SO question。

是的，比如 user1351585，更改您的 id="dialogUpload" 的名称并在 web.xml 中添加以下代码：

<filter>
        <filter-name>PrimeFaces FileUpload Filter</filter-name>
        <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>PrimeFaces FileUpload Filter</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
