Create (or verify existence of) Course Offering(s) in Draft state.
In Manage Course Offerings, enter Term and Subject codes, click Go.
Verify resulting list includes COs in draft state.
Click "Approve Subject Code for Scheduling" link.
EXPECTED: Confirmation lightbox appears, followed by successful change of state for COs from Draft to Planned.
ACTUAL: Process begins and hangs, occasionally resulting in stacktrace.
Note, also tested selecting individual COs and Approving for Scheduling. Lightbox appeared, and process seemed to complete, but Draft COs remained in Draft state.
