Either this issue should be catched when the event is being entered or the ical exporter should omit this empty list. Kronolith already does that. If the event is saved with weekly recurrence, and no weekdays have been set, the weekday of the start date is used. How did you enter that event?

i everyone, while playing with iCal4j under Android I discovered that kronolith generates output which is violating RFC5545. In the .ics file one of my appointments reads: BEGIN:VEVENT DTSTART:20111024T151500Z DTEND:20111024T163000Z DTSTAMP:20120304T202030Z UID:20CD3890-7228-4D06-A305-3BF4A9B8EB69:E306E14E-FBB6-49FE-B37F-8CB3035CCB 18 CREATED:20111010T180609Z LAST-MODIFIED:20111010T180609Z SUMMARY:Test CATEGORIES:Kalender CLASS:PUBLIC STATUS:CONFIRMED TRANSP:OPAQUE RRULE:FREQ=WEEKLY;INTERVAL=2;BYDAY=;UNTIL=20111219T225959Z END:VEVENT According to RFC5545 (http://tools.ietf.org/html/rfc5545#page-38), the RULE line is invalid as there is at least one list element expected when the BYDAY field is present. Please see the attached screenshot which shows the event in kronolith. I know, that rule does not make sense since there will be no repetitions when no weekday is selected BUT nevertheless this should not result in an unparsable ical file. Either this issue should be catched when the event is being entered or the ical exporter should omit this empty list.
