jsf - p:commandLink fails to open page in new window/tab

I'm trying to create a link to open a new page in a different window/tab and display some msg from backing bean but fail to do it, wonder know why?

here is my xhtml file:

<html:composition xmlns="http://www.w3.org/1999/xhtml"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:p="http://primefaces.org/ui"
  xmlns:c="http://java.sun.com/jsp/jstl/core"
  xmlns:ui="http://java.sun.com/jsf/facelets">
  <h:body>
    <h:form id="form66">
    <p:commandLink actionListener="#{testing.getMessage}" action="msg.xhtml" target="_blank">get Msg</p:commandLink>
    </h:form>
  </h:body>
</html>

here is my Msg.xhtml page

<HTML xmlns="http://www.w3.org/1999/xhtml"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:p="http://primefaces.org/ui"
  xmlns:ui="http://java.sun.com/jsf/facelets">
  <h:head>
    <title>testing</title>
  </h:head>
  <h:body>
    <div class="div">
      <p:panel>
        <f:facet name="header">
          testing
        </f:facet>
        <div class="paddingForPanel">
          <h:outputText value="#{testing.msg}" escape="false"/>             
        </div>
      </p:panel>            
    </div>
  </h:body>
</HTML>

here is my testing.java

public void getMessage() {      
    this.msg = "haha";
}

private String msg;
public String getMsg() {
    return msg;
}
public void setMsg(String msg) {
    this.msg = msg;
}


the code above fail to open a new tab/window, I try to do like below, it success to open the new page in new tab but the msg is empty, when I debug, it got success call the listenner getMessage, I wonder know why the msg is empty in the msg.xhtml page? Thanks in advance....

<p:commandLink actionListener="#{testing.getMessage}" oncomplete="window.open('msg.xhtml')">broadcast Msg</p:commandLink>

<p:commandLink> has some ajax issues, Use <h:commandLink> instead.

 <h:commandLink actionListener="#{testing.printMessage}" action="/Msg.html" target="_blank">get Msg</h:commandLink>

changed <p:commandLink> to <h:commandLink> and your code is working fine.
