A behaviors perspective

I am working with behaviors right now, and I have created some extra functionality for CFormModel inside a behavior.

Is it correct that a behavior does not know anything about the class that it is attached to, unless you register events? F.ex. inside the behavior, I cannot call $this->getAttributes() of the model that it is attached to?

Did you try getOwner() ?
