I presume both VEVENTS are enclosed in the same VCALENDAR object, are they? That's correct behavior. In this case both events *must* have the same UID because it's essentially the same event (just with an exception). The exception instance has a RECURRENCE-ID to specify the exact instance of the event that is replaced by the exception. cheers Marten Am 02.04.2014 08:39, schrieb Johan Vromans:
Hi,
I use Business Calendar Pro on Android. I change one occurrence of a repeating appointment to a different time and now I have a duplicate ID on the DAViCal server:
BEGIN:VEVENT CREATED:20140106T230106Z SUMMARY:**** TRANSP:OPAQUE CLASS:PUBLIC DTSTART;TZID=Europe/Berlin:20140226T093000 LOCATION:**** STATUS:CONFIRMED EXDATE:20140312T083000Z EXDATE:20140326T083000Z EXDATE:20140319T083000Z RRULE:FREQ=WEEKLY;WKST=MO;UNTIL=20141224T083000Z DURATION:PT2H30M LAST-MODIFIED:20140320T214312Z DTSTAMP:20140320T214312Z SEQUENCE:3 UID:bkdiwaiy-cmbs-xjpc-pe24-gd16ybt4mfeu END:VEVENT

This was the original event:
BEGIN:VEVENT CREATED:20140106T230106Z SUMMARY:**** TRANSP:OPAQUE CLASS:PUBLIC DTSTART;TZID=Europe/Berlin:20140226T093000 LOCATION:**** STATUS:CONFIRMED EXDATE:20140312T083000Z EXDATE:20140326T083000Z EXDATE:20140319T083000Z RRULE:FREQ=WEEKLY;WKST=MO;UNTIL=20141224T083000Z DURATION:PT2H30M LAST-MODIFIED:20140320T214312Z DTSTAMP:20140320T214312Z SEQUENCE:3 UID:bkdiwaiy-cmbs-xjpc-pe24-gd16ybt4mfeu END:VEVENT
Can I blame this to Business Calendar Pro?
