In this demo
I edited an occurrence of a recurring event. The event is to run from 1100-1200 the 2nd day of every month. I opted to create an exception and set the event to run from 1200-1300. Then I clicked the recurrence checkbox and clicked save.
As you might expect from the date of the initial exception forward I have 2 copies of the envent. One running 1100-1200 and the other from 1200-1300.
I seems to me that we don't really want recurrences set up as exceptions to existing recurrence events. I've (obviously) not been able to examine what has been written to the recurrence rule of the master event, but I'll bet it doesn't match the events that my actions caused to be created.
Is this a bug?
Do I win a prize? :-)
In the short term, why might be the best way, when adding/editing a recurrence exception, to hide the recurrence checkbox?
