authlogic_facebook_connect breaks authlogic-oauth

[joelmahoney]

after installing the authlogic_facebook_connect plugin, the oauth login with Twitter method no longer works. the error originates at authlogic_facebook_connect/lib/authlogic_facebook_connect/session.rb:132:in `authenticating_with_facebook_connect?'

here's the error:
NoMethodError in User sessionsController#create
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.+

here's the stack trace:

any suggestions?

I think I ran into something similar. My fork has a hook so that you can turn on/off facebook login: http://github.com/agibralter/authlogic_facebook_connect/commit/9758277409849f8282f096f55c22ba8cd17c149d

Here is an example of how I use it: http://gist.github.com/360833

I believe it is because of a bad design decision of auth_logic itself.
See http://github.com/binarylogic/authlogic/issues#issue/58 (and vote it up or comment!)

I switched to http://github.com/jbasdf/authlogic_facebook_connect and everything worked fine (note that you need an additional User field compared with the kalasjocke version: add_column :users, :facebook_session_key, :string)
