Hi, Yes, I had the very same problem, I had to restart org-caldav from scratch a few times (org-caldav-delete-everything, wait a bit for caches to empty, and then eventually it worked).
In the meantime I also tweaked the way org-caldav manages UIDs to exploit the fact that multiply occurring events are now exported multiple times in ox-icalendar, everything works out well if only org->ical is used. One thing remaining, on ical->org sync, there is an issue that makes the next sync erase the event on ical and upload it again, under another id (and with the info not generated by org-caldav missing, of course). I think I know how to fix it, just need to find some time ... I will send what works to the list. (In the meantime, David, don't pull my second pull request, it is not right.) /v -- Vincent Beffara On Tuesday, March 12, 2013 at 07:21 , Julien Cubizolles wrote: > Vincent Beffara <vbeff...@ens-lyon.fr (mailto:vbeff...@ens-lyon.fr)> writes: > > > ... sorry for replying to myself like this - here is a patch that seems to > > work: > > I'm still running into problems even with this patch, but I'm not very > sure where they lie.
