I would like to be able to report to a 3rd party product using SOAP if an issue is currently scheduled in an active Sprint. I can report if it is or was ever in a Sprint but I can't tell if that sprint is active.
Also, the act of putting an issue in a Sprint is not a Transition and so does not throw any notifications that something has changed that would recalculate the field.
Ultimate purpose would be to flag to third party product that certain fields should not be touched since the issue is scheduled to be worked on.
Backup plan is to have 3rd party product recognize when the issue is actually being worked on by a developer since that is a transition to the "In Progress" state.
