Layout, scrollbar and regression ?

Question

Hello,
I was very surprised to see the following example didn't produce the expected result :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
   xmlns:mx="http://www.adobe.com/2006/mxml"
   layout="absolute"
   >
      <mx:VBox x="200" width="50%" height="50%" backgroundColor="0xFF0000" >
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
         <mx:Label text="blabla" />
      </mx:VBox>
</mx:Application>
Here, I'm expecting the VBox to have a scrollBar since its contentPane is definately higher than what I'm trying to size it ( 50% height of a small browser window )
Yet, the scrollbar belongs to the Application.
The exact same example using Spark controls has no scrollbars at all.
What's happening ???

hi,
for my way of thinking it is working correctly, there are absolute co-ordinates in play so the vbox will create its minimium required coordinates and then size its bigger if the parent container is larger than twice the size of the boxes required minimium measurements.
<mx:VBox x="200" width="50%" height="{height/2}" backgroundColor="0xFF0000" >
now the vbox has its height bound to a dynamic setting and its scrollbars will appear if required.
