Hello,
In our Jira we need to have like issue's reporter more than one user.
I've created user picker custom field for adding this functionality like "Managing Issues via Group Ownership" from this article: https://confluence.atlassian.com/jira060/how-do-i-assign-issues-to-multiple-users-370705091.html
I've configured email notifications, and it's working well.
I just can't configure to be visible of issue on "My open issues" page for users picked in issue's user picker custom field.
It means that issue on "My open issues" page visible only for one user picked in standard "Reporter" field, but not for other users picked in custom (additional) user picker custom field.
Thanks!
