[flexcoders] A question about ViewStack

[al-al :D]

Is it possible to choose which stack to display first in a ViewStack?

for example

<mx:ViewStack id="myViewStack">
   <mx:Canvas id="firstCanvas">
      <mx:DataGrid />
   </mx:Canvas>

   <mx:Canvas id="secondCanvas">
      <mx:Form />
   </mx:Canvas>
</mx:ViewStack>

is it possible to choose secondCanvas to display first during creationComplete 
event? I have tried myViewStack.selectedIndex = 1 or even 
myViewStack.selectedChild = secondCanvas, but what happens is that the 
firstCanvas displays first, then it just goes to secondCanvas. I would like to 
skip the displaying of the firstCanvas

Thanks in advance! :D
