restful_authentication setup using aasm gem

Hi, I installed the restful_authentication plugin using the aasm
option instead of stateful and I can't seem to get it working. I keep
getting stating

Event 'register' cannot transition from 'pending'

it appears to be from a lack of code in my user model that I believe
installing restful_authentication with stateful does for you. Does
anyone have some notes they can share on how they configured this? I
haven't been able to find anything current on google.
