Navigation Problem in JSF - Urgent, pls help

Question

hi,
I have a problem while navigating into a popup using a custom commandLink which opens the popup.The problem is that when i close the popup and return to the parent JSF and click any button or link in the parent, the page navigates to the page that was shown in the popup. This is my custom component:
<hl:helplink id="alternateIdHelpLink" rendered="true" actionListener="#{helpBean.handleEvent}" value="Help" action="helpNeeded" target="NewWin" onclick="javascript:openPopup();"></hl:helplink>I have specified the navigation 'helpNeeded' inside the faces-config file which navigates to the page that is shown in the popup. So the problem is that i am unable to navigate to any other page after i open the popup(even after closing it).Can anyone pls find a solution for this problem.
thanks and regards

Thanks Sergey.Smirnov for the code..but its not working :-(...
This is my javascript for opening the popup in my help.js file:
function openPopup() {
    var windowDefn = "width=800, height=400, location=no, menubar=no, status=no, toolbar=no, scrollbars=no, resizable=yes";
    win=window.open('',"NewWin", windowDefn);
}On clicking the Custom Command Link the popup is opened. But then when i return back to the parent and click any other link or button the contents inside the popup is being displayed.
<hl:helplink id="alternateIdHelpLink" rendered="true"  value="Help"  onclick="openPopup()" action="#{helpBean.execute}" target="NewWin" actionListener="#{helpBean.handleEvent}" ></hl:helplink>I tried to hard code the path of the jsf file into the popup but that gave an error that 'Page Cannot be Displayed'.
I tried to get the path of the JSF using the contectPath as follows:
var path= <%= renderResponse.encodeURL(renderRequest.getContextPath() + "/pages/epsHelp.jsp" %>;
window.open('"+path+"','helpPopup','height=200,width=400,status=no,toolbar=no,menubar=no,location=no,scrollbars=yes');",null);When i viewed the source of the parent page the javascript was showing the correct context path ie "/help/pages/myjsf.jsp". What might be the issue.Can you please help..
Thanks
