An issue may lose all its custom field values.

1. create one required and one non-required issue custom field
2. create a tracker that uses these two custom fields
3. create a new issue using the tracker and enter values into both custom fields
4. when the issue is shown click on update
5. with (for example) "Firefox DOM Inspector" remove the required custom field from the DOM
6. submit the form
7. error message "<<custom field>> can't be blank" appears (which is correct)
8. enter the ticket id in the search field to reload the page

1. the issue's custom fields are blank (and no journal details are written)

1. the issue should not have changed
