Discussion: avatar.getDetails question

Hi everyone, I contributed the AS3 SDK and I'm poking around with some other related stuff, but I've run into a roadblock with avatars. I've loaded up my avatar with avatar.getDetails and I'm trying to load a piece .swf (a hat in this case). I assumed that "article_class_name" would be the linkage identifier in the swf, but the following approaches didn't work:

- Just adding the loaded swf to the stage
- LoaderInfo(e.target).applicationDomain.getDefinition("hat_01_panda")
- LoaderInfo(e.target).applicationDomain.getDefinition("hat_01_panda_dataClass")

No security errors are thrown and I don't get anything visual added to the stage.
How do I load the visual representation from one of the avatar piece swfs?
