Primefaces grow with socket

In some place in the page puta the grow. Generally the grow is in the form for update with actions. This example make this with javaScript.

<p:growl widgetVar="growMessage" showDetail="true"/>

One socket to listener the channel and call the javascript function.

<p:socket id="socketweb" onMessage="handleMessage"  channel="/notify" />

Now the messages are inserted by the function handleMessage. When the function show() is called the message appear in the client.

  <script type="text/javascript">
            function handleMessage(facesmessage) {
            facesmessage.severity = 'info';
            growMessage.show([facesmessage]);
        }
  </script>

In managed bean:
To get the Context use pushContext MORE.

The send message use FacesMessage and send to client the message.

 public void send() {
        FacesMessage message = new FacesMessage();
        message.setSeverity(FacesMessage.SEVERITY_INFO);
        message.setSummary("Message");
        message.setDetail("Message Detail");
        pushContext.push("notify", message);
}
