Okay, I admit, the subject is a LITTLE misleading. Your original page for the stoplight renderer (http://www.quietlyscheming.com/blog/charts/data-based-renderers/ ) does still work. But a slight derivative of it now seems to fail.
I'm specifically referring to setting the itemRenderer at runtime. Using setStyle("itemRenderer", ...), the chart never seems to update. Below is my example based on your example. I show three charts. The first is using a switchable item renderer, the second is using MyStoplightItemRenderer, the third using MyStoplightItemRenderer2. The radio button is supposed to switch the first chart back and forth these two. This used to work under the beta. Now it seems to have no effect.
Can you confirm this is a bug in Flex? I'm not going to post it to the bug webpage yet in case you just changed how you are supposed to approach this problem.

switch (rendergroup.selectedValue) {
case "Renderer1":
pie.setStyle('itemRenderer', new ClassFactory(MyStoplightWedgeRenderer));
break;
case "Renderer2":
pie.setStyle('itemRenderer', new ClassFactory(MyStoplightWedgeRenderer2));
break;
}
