[Kolab-devel] [issue3406] Horde: attendee cannot change appointment

[Albrecht Dreß]

New submission from Albrecht Dreß <albrecht.dress at lios-tech.com>:

I ran reproducibly into a situation where attendees cannot update appointments
when they are moved.  I use kolab 2.2, and all users shall manually process
invitations.  Consider two users "a" and "b":

- "a" creates an appointment, invites b and checks to send the invitation.
- "b" accepts the appointment (in the web mail section), which is properly added
  to the calendar.
- "a" opens the appointment again in the calendar, changes the time and sends an
  update to all participants;
- "b" opens the message in the web mailer and tries to accept.  The following
  messages appear:
  [!]Beim Importieren des Termins ist ein Fehler aufgetreten: Existiert bereits.
  [v]Antwort versendet.
- "a" receives the "accept" message from "b".  The appointment in "a"'s calendar
  is properly shifted;
- the same appointment in "b"'s calendar still has the old time.

Result: although "b" properly accepted the changed appointment, the calendar
data doesn't get updated.  This is of course a source of endless confusion!
