JForm - Media: image alt parameter not working

[Giuse69]

In the JForm Media field, the "image alt" attribute can be filled with the value of another field, but that seems not to work: the value of the field is somehow read since it is used for the title attribute (set with "Image title = auto") but it is not replicated into the alt attribute, and infact in the php log there is an error: PHP Notice: Undefined property: stdClass::$do in /var/www/html/plugins/cck_field_validation/ajax_availability/ajax_availability.php on line 49 Thanks
