REPRODUCIBILITY (% or how often): ??
BUILD ID = OS VERSION (Settings > About product): 4.4.0.58

UI LANGUAGE: German
REGRESSION: (compared to previous public release: Yes, No, ?): ??

DESCRIPTION:

I just was correctly remined on an upcoming event. However, the event is not visible in the Calendar

PRECONDITIONS:

I have synched my calendar by importing an .ics file. The event is a reoccurring event that was changed multiple times.

STEPS TO REPRODUCE:

EXPECTED RESULT:

Event should be visible in Calendar (and alarm should be triggered)

ACTUAL RESULT:

Only the alarm is triggered, implying that the import of the calendar entry half-way worked

ADDITIONAL INFORMATION:

The .ics file for the entry looks as follows:

Thanks for the report. May you check the ICS data you pasted ? It is not terminating with END:VCALENDAR.

[JoOppen]

Thank you Damien, you are right. I missed to copy the entire .ics file. Since it is rather long, I just send you a private message.

I’m proposing a fix with https://github.com/sailfishos/mkcal/pull/27

The issue comes from the fact that the event is defined with RDATE only, starting in January. The events are not showing in the calendar, because, the incidence is actually loaded only when swiping to January, and then the ranges for the other months are already flagged as loaded in nemo-qml-plugin-calendar, so the occurrences for these ranges are not recomputed (and thus not displayed). The alarms are set because the event actually exists in the database, but are not shown due to the bug.

Thanks for highlighting this issue @JoOppen, and for the nice fix @dcaliste. Since this is now merged, I’ve tagged this bug as fixed.

It should make it in to the next release (after 4.4.0).

[JoOppen]

Great, thank you!

As we are at it, there is no “ORGANIZER”. On 4.5, if you add it, while importing, it warns you about not being able to edit, but then it gets lost and it is possible to edit the event. Not so on 4.4, there you can only delete. (The toggle to remove attendees has no efect.) @flypig VALARM is also not shown after the import (4.5).
