As Patrick, I want to assign issues to a version

• permissions
• only one version can be associated with an issue (using this feature): fixVersion is replaced
• can assign multiple issues to a single version easily
• what happens when multiple issues from multiple projects are dragged?
  • don't allow drop on version panel
  • possibly explore additional message or change cursor
• what happens when an issue from PROJA is dropped onto PROJB?
  • don't allow drop on version panel
  • show message
• able to drag issues from active sprints or future sprints or backlog
  • refer to comments below re: dialog when destructively updating

Note:

• IE8 experience may not be as good due to bad drag and drop performance
• consider messaging for invalid drop targets

Development Notes

Q: What if the version list is stale and a version doesn't exist anymore/was archived?
A: We show a "Issue doesn't exist" message and we reload the issues list

Q: What if an issue was converted to a subtask or epic?
A: We attach it anyway

Q: What if the issue is already part of a sprint?
A: We allow it

Q: Need to make sure the issue is not reranked if drop on version fails.
A: We always cancel ranking after drop on versions even if it fails

Q: What if a group of issues is dropped but one or more fail to be added? What happens to the rest and how do we notify the user?
A: We don't update anything and we show a message saying that the user doesn't have the permission to update the issue(s)

Q: Are the dropzones properly hidden when the version tab is hidden?
A: yes

Q: Does drag and drop work well if quick and/or instant filters are on?
A: yes, no direct influence
