Okay, after a bit of digging I think what we need to do is remove the "event.setDueDateTime(alarm.date);" line from ubuntu-ui-toolkit's AlarmsAdapter::organizerEventFromAlarmData().
Here's an abbreviated example of a vtodo written to tasks.ics by ubuntu- clock-app --> ubuntu-ui-toolkit --> qtorganizer5-eds: BEGIN:VCALENDAR^M CALSCALE:GREGORIAN^M PRODID:-//Ximian//NONSGML Evolution Calendar//EN^M VERSION:2.0^M X-EVOLUTION-DATA-REVISION:2014-02-25T04:39:19.361663Z(2)^M BEGIN:VTODO^M UID:20140225T043915Z-3142-32011-1543-9@ubuntu-phablet^M DTSTAMP:20140225T043915Z^M DTSTART:20140224T060000^M DUE:20140224T060000^M RRULE;X-EVOLUTION-ENDDATE=19700101T000000Z:FREQ=DAILY;COUNT=-1^M SUMMARY:Alarm^M CREATED:20140225T043915Z^M END:VTODO^M END:VCALENDAR^M indicator-datetime tries to find calendar events within a certain time window by using e_cal_client_generate_instances(), which doesn't find the above VTODO when searching in the date range [2014-02-24 22:52:33...2014-03-24 22:52:33] e_cal_util_get_component_occur_times() (in evolution-data- server-3.10.1/calendar/libecale-cal-util.c) has a special rule for VTODO items, looking for the ending range by taking the higher value of "completed" or "due": > if (kind == ICAL_VTODO_COMPONENT) { > .... > e_cal_component_get_completed (comp, &tt); > .... > e_cal_component_get_due (comp, &dt_due); > .... > max_time = MAX (completed_time, due_time); Since "completed" isn't set, EDS returns "due" as the end. "due" comes from qtorganizer5-eds's qorganizer/qorganizer-eds- engine.cpp's QOrganizerEDSEngine::parseDueDate()'s call to e_cal_component_free_datetime(). That call appears to come from ubuntu-ui-toolkit's modules/Components/plugin/adapters/alarmsadapter_organizer.cpp's AlarmsAdapter::organizerEventFromAlarmData() function calling "event.setDueDateTime(alarm.date);" If you remove the single line "DUE" from the above VTODO, e_cal_client_generate_instances() is able to find it using the same date range mentioned above. ** Also affects: ubuntu-ui-toolkit Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283859 Title: Updated recurring alarm values are not reflected in the indicator until phone reboot To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-datetime/+bug/1283859/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
