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....

I do it like this:

<p:commandLink id="link" actionListener="#{testing.getMessage}" 
    oncomplete="popupwindow('msg.xhtml', 'newwindow');" >  
    <h:outputText value="broadcast Msg" />
</p:commandLink>

With some javascript:

<script type="text/javascript">    
function popupwindow(url, title) {      
    window.open(url , title, "toolbar=no, scrollbars=yes, resizable=yes, top=170, left=170, width=800, height=600");        
}    
</script>

In this example you open a new window, hope its helps!

<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.

If you are using remotecommand then you can do like this

<p:remoteCommand name="lookAndBookNewTab"
     process="@this" action="#{lookAndBookMB.onPageLoadForNewTab()}"
     rendered="#currentUserManager.
     hasPermission('LookAndBook','View')}"             update=":messageForm:growl" />

And my javascript:

<script> 
    if(event.ctrlKey &amp;&amp; event.shiftKey &amp;&amp; event.keyCode == 119) {
     lookAndBookNewTab(); 
    event.preventDefault();
</script>

ServerSide action method:

public String onPageLoadForNewTab(){
    HttpServletRequest req = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest(); String url = req.getRequestURL().toString();
        url=(url.substring(0, url.length() - req.getRequestURI().length()) + req.getContextPath() + "/"); url=url+navigationpagename+".jsf"; RequestContext.getCurrentInstance().
        execute("window.open('"+url+"','_blank')");** 
    return ""; }

Both are not working so issue is not in primefaces ajax. Issue in target attribute of p:commandLink its not working...

<p:commandLink value="New Window" ajax="false" target="_blank" action="test"/>

<p:commandLink value="New Window" target="_blank" action="test"/>

SO we have to use

<h:commandLink value="New Window" target="_blank" action="test"/>

Try this in your controller code, it worked for me perfectly.

HttpServletResponse res = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
            HttpServletRequest req = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
            String uri = req.getRequestURI();
            res.getWriter().println("<script>window.open('" + myUrl + "','_blank', 'location=yes,height=600,width=800,scrollbars=yes,status=yes'); window.parent.location.href= '"+uri+"';</script>");
            FacesContext.getCurrentInstance().responseComplete();
