Drawing event on an actor behavior not firing

Any reason why "when drawing" block wouldn't work on an actor behavior? The actor is on the scene and the behavior is attached. I took everything out of the "when drawing" block except for a log print line. Nothing shows in log so it's not even being called. Should the drawing event be automatically called for an actor or do you need to explicitly call it from the scene drawing event?

It should automatically be called as long as the actor is on-screen.

Grrr. Has physics set to minimal instead of simple on it.
