Slightly OT: What is wrong with this appointment
Hi, The following appointment works fine in InfCloud and Android, but it doesn't show up on iPad. Is there anything wrong with it?

Hi Johan, Technically this VEVENT violates RFC5545 <https://tools.ietf.org/html/rfc5545#section-3.6.1>. DTEND and DURATION are mutually exclusive, only one may appear NOT both (or neither). On 01/29/2015 05:19 PM, Johan Vromans wrote:

Not sure if that's the actual reason, but the event has DTEND and DURATION , which is invalid. These properties are mutual exclusive. Marten Am 29.01.2015 um 14:19 schrieb Johan Vromans:

Apple is known to be picky, so this may very well be the reason this appointment does not show on iPad. How to reproduce: Create the appointment using CalDAVzap or InfCloud: duration 2hours, repeating weekly on MO and TH for some time (e.g. until 31-12-2015). The appointment now has only DTEND. On Android, modify the appointment, all occurrences, from 2hrs to 1hr. Now it has both DTEND and DURATION. Could this be a problem of the Android CalDAVsync app? -- Johan
Yes, that's probably a CalDAV-Sync issue. Android requires a DURATION for recurring events. Of course the DTEND should be removed in that case. Is that our CalDAV-Sync or the other one? I'll check our code and fix it if necessary. cheers Marten Am 29. Januar 2015 23:36:07 PST, schrieb Johan Vromans <jvromans@squirrel.nl>:

Yes, it's your CalDAV-Sync. Thanks for looking into it. -- Johan
Hi Johan, please tell me which Android version (or Custom ROM) and which calendar app you use. You can reply off-list to marten <at> dmfs.org cheers Marten Am 30.01.2015 um 17:20 schrieb Johan Vromans:
