No problem, typos get us all, and it always seems like it has to be something major
On the initializeNotifier vs onRegister, the former is merely the first opportunity for you to make calls to your facade. Its after construction but before registration.
The latter is later still and is right after registration, so you can be sure that if your facade manipulations result in the Proxy or Mediator being retrieved (or notified if its a mediator) by some other actor that it will be available.
Generally you don't need to use initializeNotifier, its just an earlier hook than onRegister.
