Page Flows - opening new windows - losing context values

Question

Hi.. Anyone face this -?
I have a page flow that gets some data from the database and displays it in a grid. The page has a print button that should open a popup with a printable version of the grid. I am storing the rowset in the page flow as an instance variable. Now when I click on print, I call an action in the page flow that opens a new JSP in another window. The JSP is expecting the grid from the page flow context. However, it seems like in the new window, a new version of the controller is getting instantiated, with the rowset being null.
How would I get around this?
Thanks

I've had success with the following so far--think it works around the instance label limitation:
* Popup window action. Redirect set to true to unwrap request from portal.
* @jpf:action
* @jpf:forward path="/portlets/full/path/to/this/action/displayNumber.do" name="jumpout" redirect="true"
* @jpf:forward path="Number.jsp" name="success"
protected Forward displayNumber() throws Exception
     String s = this.getRequest().getParameter("jpfScopeID");
     if(s==null || s.equals("")){
          Forward fwd = new Forward("jumpout");
          pageFlowVar x = "test";
          PortletBackingContext ctx = PortletBackingContext.getPortletBackingContext(this.getRequest());
          fwd.addQueryParam("jpfScopeID", ctx.getInstanceLabel());
          return fwd;
     } else {
          Forward fwd = new Forward( "success" );
          fwd.addPageInput("pageInput", x);
          return fwd;
}
