VerticalLayout.updateDisplayList() as this snippet
```
if ((layoutTarget.numElements == 0) || (unscaledWidth == 0) ||
(unscaledHeight == 0))
{
setRowCount(0);
setIndexInView(-1, -1);
if (layoutTarget.numElements == 0)
layoutTarget.setContentSize(Math.ceil(paddingLeft +
paddingRight),
Math.ceil(paddingTop +
paddingBottom));
return;
}
```
and in our case unscaledWidth of the VGroup is 0, so measurement of inner
labels is not attempted. But even setting the width was not enough. I needed to
override SideLink.measuredHeight like so
```
override public function get measuredHeight():Number
{
return 17;
}
```
