Subject: Fixes for importing iCalendar files with RECURRENCE-ID set.
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=d8d246e45b047210bac2e6292f6f563d7922eee7;p=horde.git

Fixes for importing iCalendar files with RECURRENCE-ID set.

The original recurring event must be imported before any instances of
RECURRENCE-ID exceptions or the original event will not be found to modify.
