I should know better by now to never declare victory until you tried your
test app solution in your REAL app.
A problem occured that if your popupbutton is embedded in another control,
the "y" value will no longer be in the same frame of reference as the popup,
which is no a child of the same control as the popupbutton. So this may not
be the BEST way to do it, but it works:
gr.validateSize(true);
var verticalGap:Number = grid.getStyle("verticalGap");
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
if (grid.localToGlobal(new Point(0, 0)).y < grid.owner.localToGlobal(new
Point(0, 0)).y)
grid.y -= gr.measuredHeight + (isNaN(verticalGap) ? 0 : verticalGap);
