ActiveRecord::AssociationTypeMismatch (User(#54754560) expected, got User(#54510280))

i keep getting this AssociationTypeMismatch error. i think this could be a bug related to ruby/rails when using mixins. heres a short version of my code:

# user.rb

require 'friend_invitation' require 'friendship'

class User < ActiveRecord::Base   include FriendInvitationUser, FriendshipUser

  ... end

# friendship.rb

...

module FriendshipUser   def self.included(includer)     includer.class_eval do       has_many :friends, :through => :friendship     end   end

  # true, if other_user is a friend of mine   def friend_of?(other_user)     Friendship.between?(self, other_user)   end

  ... end

so basically I'm using modules to mixin new aspects into the User model (kinda like AOP in ruby). i believe that these mixins together with the require statements at the top of the User model file cause the AssociationTypeMismatch. if i get the error, a restart of my development server solves the problem - but that can't be the solution. any ideas where this error comes from or what to do about it?

any help very appreciated!

using require like this can bust stuff (see Required or Not ? - Space Vatican   )
