I have two projects. For each I have created a different configuration scheme.
When I look at the issue types, they are all associated to one field configuration.
And I can't figure out where to Associate all issue types in project B to field configuration B and make that in configuration scheme B.
I believe that the fact I cannot create a sub-task is due to that reason since in project A I have a custom assignee field with default user which is not part of the project B team.
