For performance reasons, renderers get validated once and not checked again, so you can't just figure out the size later. An example is in ListItemRenderer. Its internal textfield handles wordwrap correctly. The OP could just use it, but it doesn't handle html. I'd just copy the source and wire the listData.label to the htmlText.

Wouldn't measure get called again once the text component has layed out and worked out its height in a frame or 3? What's the answer? Set text.width, call validateNow() before you use text.height in renderer.measure()?
