Question

我正在尝试使用p：按下对话框，我在chrome中遇到此错误：

Uncaught Error: INVALID_STATE_ERR: DOM Exception 11 primefaces.js.xhtml:1
    PrimeFaces.widget.PrimeWebSocket.send primefaces.js.xhtml:1
    PrimeFaces.ajax.AjaxUtils.handleResponse primefaces.js.xhtml:1
    PrimeFaces.ajax.AjaxResponse primefaces.js.xhtml:1
    k.success primefaces.js.xhtml:1
    b.Callbacks.bv jquery.js.xhtml:16
    b.Callbacks.bE.fireWith jquery.js.xhtml:16
    bF jquery.js.xhtml:23
    b.ajaxTransport.send.bv

推送服务器在端口9090的jetty 8.1.5.v20120716中运行这是我的应用程序的web.xml的一部分：

<context-param>
       <param-name>primefaces.PUSH_SERVER_URL</param-name>
       <param-value>ws://localhost:9090/push/</param-value>
</context-param>

这是推送服务器的web.xml的内容：

<display-name>PUSH SERVER</display-name>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>channels</param-name>
        <param-value>importador</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>Push Servlet</servlet-name>
    <url-pattern>/push/*</url-pattern>
</servlet-mapping>

对话框的内容：

...
<h:panelGroup layout="block" styleClass="hrgi-div-form clearfix">
       <h:panelGroup id="painel" layout="block">
                <p:progressBar widgetVar="barraProgressoImportador" ajax="true"
                               value="#{modeloPopupImportadorImediatoNFe.porcentagem}"/>
                <h:outputText value="#{modeloPopupImportadorImediatoNFe.mensagem}"/>
       </h:panelGroup>
       <p:push channel="importador" onmessage="atualizarPorcentagemImportacao"/>
</h:panelGroup>
...

调用的javascript代码（只显示提醒）：

function atualizarPorcentagemImportacao(evt, data){
    alert("importado "+data);
}

最后是尝试推送的代码：

public void abrir() {
        ...
        modeloPopup.setContext(RequestContext.getCurrentInstance());
        modeloPopup.getContext().push("importador", 0);
}

我做错了吗？

ADDED 的如果它有用，这是我的推送服务器的pom.xml

您需要以下设置才能完成推送工作。

在pom.xml中：

    <dependency>
      <groupId>org.atmosphere</groupId>
      <artifactId>atmosphere-runtime</artifactId>
      <version>1.0.0.RC1</version> 
    </dependency>

在web.xml中推送servlet设置：

    <servlet>
      <servlet-name>Push Servlet</servlet-name>
      <servlet-class>org.primefaces.push.PushServlet</servlet-class>
   </servlet>
   <servlet-mapping>
      <servlet-name>Push Servlet</servlet-name>
      <url-pattern>/primepush/*</url-pattern>
   </servlet-mapping>

在这些推动必须奏效之后。
