This brings up another point. I could just add multiple
PieSeries. Unfortunately, setting a PieSeries.visible=false does not
actually take it out of the chart. Even though it's hidden, it still
affects the other series and such. This seems counter-productive.

Honestly, I'm surprised that worked in beta 3. Regardless, the series is
caching instances of the itemRenderer, and not correctly releasing them when
you switch to a different renderer. The only workaround I can see right
now is to create a new PieSeries rather than just changing the
itemRenderer.

Subject: [flexcoders] Ely: StoplightRenderer example
doesn't work right in release
Ely,
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.
