I have associated following issue types {Story/Bug/Task/Subtask} in an issue-type-scheme
In a "Scrum Default Issue Screen".
Attached is a userstory screen with way to create subtasks, but no way to create Bug under the story.
Linking a bug is not an option
Converting to a subtask is not an option.
Only thing that we need is add a bug under user story.
I remember somewhere I configured an issue type with the Screen scheme several moons ago.. not able to figure how I did that.
Any help is appreciated.
