I'm implementing custom membership provider based on this tutorial (http://docs.sitefinity.com/tutorial-create-a-custom-membership-provider). Everything is ok, except when I edit an user and change his email address, the email is not updated, while all other fields can be. I realized that all other fields belong to sf_sitefinity_profile table which is SF built-in table, but Email address is in a new table which I created for Custom membership.
I tried to subscribe UserUpdating/UserUpdated events using EventHub, but it does not work also (ProfileUpdated/ProfileUpdating work for me). Please advise.
