open id is not returning with email when using with authlogic

Question

it still shows it as an empty field

Answer 1

OpenID providers don't have to return the email address, even if you request it as required.

Does the provider informs you that your RP has requested the email address?
If not, it means that either you haven't requested it properly, or the provider has ignored the request.

If you think that it indeed does send you the email, try to find in in the return url (if returning by GET, which is most common case).
