Hello,
An user can create an issue.
There he has to fill in the reporter (user has a permission to change it, default=yourself) and a custom field user picker (called Manager).
Problem is the user can't click on the user picker icon, so he can't choose from the list.
He can type in the name, but doesn't have the list.
When the issue is created, the user can edit it.
In the edit option, the user picker works perfectly.
And also in all further actions.
Working in JIRA 4.2 standalone.
Regards,
Sir Be aka Bert.
