Question

我最近从Primefaces 4.0升级到5.0，而且我无法使用推送消息来使用5.0。我的服务器是Glassfish 4.0，浏览器是Firefox 29.0.1

我已将问题简化为一个非常简单的示例，该示例遵循用户指南中的示例。当我单击按钮发送消息时，端点已成功接收，但我收到javascript错误，文本未更新。这是错误：

与ws：// localhost：26293 / pushtest / primepush / mytest的连接？X-Atmosphere-tracking-id = 0＆amp; X-Atmosphere-Framework = 2.2.0-javascript＆amp; X-Atmosphere-Transport = websocket＆amp; X-Atmosphere-TrackMessageSize = true＆amp; X-Cache-Date = 0＆amp; X-atmo-protocol = true在页面加载时被中断。

我的页面：

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:p="http://primefaces.org/ui"    >
    <h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</h:head>
<h:body>
    <h:form>
        <h:commandButton value="send message" actionListener="#{testBean.sendMessage()}"/>

        <p:socket channel="/mytest" onMessage="handleMessage"  >

            </p:socket>
            <h:outputText styleClass="messageDisplay" id="test1" value="hello text"/>
    </h:form>
    <script type="text/javascript">
        // <![CDATA[
        function handleMessage(data) {                      
            $('.messageDisplay').text(data);
        }     // ]]>
    </script>

</h:body>

Backing Bean: 
@Named
@ApplicationScoped
public class TestBean {
    public void sendMessage() {
        Date now = new Date();
        System.out.println("sending message, now: "+now);
         EventBus eventBus = EventBusFactory.getDefault().eventBus();         
        eventBus.publish("/mytest", "complete "+now);        
    }
}

Push Endpoint: 

@PushEndpoint("/mytest")
public class PushEndPoint {
@OnMessage(encoders= {JSONEncoder.class})
public String onMessage(String msg) {
    System.out.println("received msg: "+msg);
    return msg;
}

}
