REPRODUCTION: ============= - create a new event, name it 'test', create a recurrence rule (e.g. daily, 5 times) - select the first event of this rule - open the edit dialog and choose 'this occurrence only' - rename this event, e. g. '123', and save this - now delete this event RESULT: ======= - all other events of the recurrence changed now there title to '123' EXPECTED RESULT: ================ - the events should not change there title REPRODUCIBLE: ============= - always This happens only with WCAP calendars. I can't reproduce this bug with the m6 build.
This is a server bug I will most probably file against. I fixed that working around the problem by writing all of the parent's data when the recurrence info is modified (which actually took place here: an EXDATE is added).
I checked this in the latest build, bug is fixed.
