[flexcoders] Need effect for ViewStack w/o changing the view

[joyh2002]

Hi all,

I have a viewstack like this:

<mx:ViewStack>
  <mx:Canvas id="view1" hideEffect="{fadeOut}" showEffect="{fadeIn}" />
  <mx:Canvas id="view2" hideEffect="{fadeOut}" showEffect="{fadeIn}" />
</mx:ViewStack>

The hideEffect and showEffect is triggered when I switch the views. How do I 
make the same effect when I change the contect of view1 (without changing the 
view from view2 to view1)? I'm already on view1, I change the content of view1, 
and need the same effect to signal the user that there are changes to the 
content. I don't want to create a new view.

Thanks,
Joy
