Stop repeating follow-ups

When you stop a recurrence, all repetitions of the follow-up after the occurrence you edit are deleted. If you cancel the recurrence of the 1st in a series, the pattern is deleted and the follow-up becomes a single appointment/call/task.

Integer aId = 234;
DateTime now;

NSAppointmentAgent appointmentAgent;
NSAppointmentEntity a = appointmentAgent.GetAppointmentEntity(aId);

NSRecurrenceInfo r = a.GetRecurrence();
if (r.GetIsRecurrence()) {
  r.SetIsRecurrence(false);
  r.SetPattern(0);
  a.SetRecurrence(r);
  a = appointmentAgent.SaveAppointmentEntity(a);
}
