From https://issues.kolab.org/show_bug.cgi?id=5445... if I have an iCal file with
BEGIN:VALARM ACTION:AUDIO TRIGGER:-PT15M END:VALARM
and in python do:
from kolab.calendaring import EventCal event = EventCal() success = event.fromICal(ical)
it works, but if I then try to generate XML with:
event_xml = kolabformat.writeEvent(event) error = kolabformat.error()
I got error: Failed to parse calendar! Everything works if I add ATTACH property, but according to RFC 5545 it is not required.
