AttributeError: 'AnonymousUserMixin' object has no attribute 'id'

[libbkmz]

I get this strange error randomly. To fix i clear the cookies of used domain. And now, i found the fix, after which i can't get this error again:
core.py

def _identity_loader():
    if not isinstance(current_user._get_current_object(), AnonymousUser):
        identity = Identity(current_user.id)
        return identity

To:

def _identity_loader():
    if not isinstance(current_user._get_current_object(), AnonymousUser) and \
       not isinstance(current_user._get_current_object(), AnonymousUserMixin):
        identity = Identity(current_user.id)
        return identity

When I'll get this error again, i'll post the full traceback

Somehow the AnonymousUserMixin object is being used as your anonymous user object class. This is most likely due to a configuration problem.

Any suggestions?

@libbkmz I can't make any suggestions unless I was able to see your code.

I'm not sure how you are using the access_list, but you may just need to put a @login_required decorator on the route before you apply whatever access decorator you've come up with (i.e., below it) which will redirect a non-logged in user before your access_list stuff happens.
