Creating an event that does not allow for online registration fails with an error about confirmation email.

This is a usability issue, as the "Send Email Confirmation" default is currently YES for a new event - but this field is hidden by default because is_online_registration is FALSE by default.

Suggested fix in Registration.php:

• For "new" event case (i.e. no event_page yet) - set $defaults['is_email_confirm'] to NULL (so neither yes or no is checked on the radio).
• formRule specifies that is_email_confirm must be either 0 or 1 if is_online_registration = 1 (so we know that the user made a choice).
• postProcess sets is_email_confirm = 0 IF it is not set (so this happens automatically when is_online_registration is left as 0.
