[flexcoders] flex 2 - printing. child disappers from container after i add it to my print

[bhaq1972]

Hi 
I have a PrintView template which looks like this

PrintView.mxml
--------------
<mx:VBox>
 <mx:Label />
 <mx:PrintDataGrid/>
</mx:VBox>

In my printThis() function i decide whether to add an extra child to 
the PrintView. What then happens is, it disappears from the original 
container.

public function printThis(vbox1:MyVBox, bPrint:Boolean)
{
  // create a printjob etc
  ...
  var print_view:PrintView = new PrintView();
  if(bPrint)
  {
    print_view.addChildAt(vbox1.child1, 1);//child is another VBox
    //after this, child1 disappears from vbox1 (on screen anyway)
  }
}
 
I know it some kind of reference thing but not sure what knowledge 
i'm lacking here. would love to know

regards
bod
