A sample app where the scroller does not show up. Is there any sane way of using a scroller in a constrain based layout?
<?xml version="1.0" encoding="utf-8"?>
<s:HGroup left="0" right="0" top="0" bottom="0">
<s:Scroller left="0" right="0" top="0" bottom="0">
<s:VGroup>
<s:BorderContainer borderColor="0" width="500" height="500"/>
<s:BorderContainer borderColor="0" width="500" height="500"/>
<s:BorderContainer borderColor="0" width="500" height="500"/>
</s:VGroup>
</s:Scroller>
</s:HGroup>
