Popup New Window with CommandLink onclick attribute

["Romanowski, Tim" <ti...@lmco.com>]

What I would like to do:  
I am trying to popup a new window each time a cell in my datatable is
clicked.  I fail when attempting to bind (set) a value before the window
is opened; it's the standard master/detail scenario discussed here
several times in the past.  The only difference is trying to popup the
window.

Problem:
I am able to popup a window by calling some javascript via the onclick
attribute of the commandLink.  I have tried using updateActionListener
to set the value of the current cell's value as is normally used to set
a value befor executing an action.  However, because I am using the
onclick attribute to open a new window, the window seems to be rendered
before the updateActionListener actually sets the value.  Since the
target attribute doesn't work, I can't do something like
'target="this.form._blank".  I am using Apache Beehive for my pageflow
controller, and am attempting to set a value in my controller class; the
idea is that when the popup page is created, the new page's backing bean
can grab the value I previously set in the controller via the
commandLink. 

I'm new to webapp development and jumped into JSF/Beehive headfirst, so
my misunderstanding of javascript may be the culprit.  Any help would be
greatly appreciated.

Here's a sample of the code:

<t:column>
  <f:facet name="header">
    <f:verbatim>Header Name</f:verbatim>
  </f:facet>
  <h:form>
    <h:commandLink onclick="myJavaScript(#{dbRow.cellValue})"
        value="#dbRow.cellValue}">
        <t:updateActionListener
property="#{pageFlow.thisSetsValueInMyController}"
value="#{dbRow.cellValue}" />
    </h:commandLink>
  </h:form>
</t:column>

Javascript (currently in same page for trying this):

<script type=text/javascript">
Function myJavaScript(cellValue){
  popup =
window.open("http://localhost:8080/XYZ/controller/goNewPage.do", 
                                  "page name",
"height=300,width=300,resizable=1,toolbar=no,menubar=no");
  popup.focus();
}
</script>

this is because you are doing a "non-postback" request
Phase 1 (RESTORE_VIEW) goes directly to Phase 6 (RENDER_RESPONSE)
