No, creating the exception is not necessary. Suppose you have a VEVENT with RRULE which expands to a regular start time of one recurrence at, say, 20110912T090000Z. Then the detached recurrence must have RECURRENCE-ID:20110912T090000Z and it will *replace* the regular recurrence without having to add an EXDATE to the parent. That's part of the iCalendar 2.0 semantic. > Note the issue wasn't shown when you did it, but only when you restart > evolution and e-calendar-factory, because the backend sends you the > master object without exceptions and a detached instance. I still think that the recurrence generation is really at fault. This seems to be a regression, the bug does not occur in Evolution 2.32.4. > Do you think there is a better solution for this? I would have to investigate some more. I compiled Evolution master in a chroot, but I haven't tried to actually run it yet - this is my main work machine. No promise that I'll get around to it soon. I want to release SyncEvolution 1.2 or at least the final release candidate this week before going on vacation end of the week. -- Bye, Patrick Ohly -- patrick.o...@gmx.de http://www.estamos.de/ _______________________________________________ evolution-hackers mailing list email@example.com To change your list options or unsubscribe, visit ... http://mail.gnome.org/mailman/listinfo/evolution-hackers
