Adding a child to spark scroller in as

Question

Tried adding a child (group) to the scroller class by using the viewport function but it didnt seem to work. is there a way to add a scroller via as and then adding a group as its child ? right now the scroller was added to the stage using addElement and the group was added as its viewport. I tested by adding a textarea to the group and it did display. however i didnt see any scrollbars even though the textarea was 3000 pixels high.

Hi,
The following code is one way you can set up a scroller, when you add something to the group the scrollbars will appear if that object exceeds the scroller boundaries. When you add the oversized child component(I used a list here for simplicity) the scrollbars will kick in.
