Missing event for a sprint when it changes its the state property from Closed to Active (sprint reopening)

Hi there!

I’m wondering if I have a way to catch a user’s action when s/he is re-opening a sprint in order to process it in my plugin?

I’ve checked GreenHopper API through its first stable release (8.5.5) to its current state (9.11.0) and I haven’t found any related events. SprintUpdatedEvent is not fired (it makes sense due to Sprint.getState() has changed its value). Even SprintEvent, which is general for all sprint-related events, is not arriving.

Any thoughts about workaround for this bug?
