You don't need to call Accept, FNH does that.
Your Accept method is wrong. Where did you find that sample? This behaviour
changed as part of the release, Accept methods are now not required by
default, and you need to explicitly specify them if you want to use them.
You can read about it under conditional applying of
conventions<http://wiki.fluentnhibernate.org/Conventions#Conditional_applying_of_conventions>
