When I mark an issue as RESOLVED (using either the Greenhopper task board or JIRA) then my issue burndown reduces by 1. This is what I expect.
However, when I then mark the same resolved issue as CLOSED, the issue burndown returns to original level. It is as if I have REOPENED the issue.
If I RESOLVE the issue again, the issue count goes down but again on CLOSE the count returns to original value.
My only solution is to leave all issues RESOLVED and never mark them as CLOSED.
Can anyone shed any light?
