In the sfFacebookConnectAuth module, line 56 of lib/BasesfFacebookConnectAuthActions.class.php file, I found this:
$create_automatically = !sfConfig::get('app_facebook_redirect_after_connect', false);
$sfGuardUser = sfFacebook::getSfGuardUserByFacebookSession($create_automatically);
It seems to me that maybe we are not fetching the correct configuration? Do you remember what the intention was, Fabrice? Should we just replace it with another configuration key? Or am I perhaps misinterpreting the meaning of "redirect_after_connect"?
