I have been able to reproduce this, and am looking for validation before submitting a bug report:
Version 2.2.17a User 1, Calendar 1 User 2, Calendar 2 User 1 has full privileges to Calendar 2. User 1 creates a new event on Calendar 2 (while logged in as User 1) and then invites herself (User 1) to the event. User 1 then accepts the invitation on Calendar 1. Circumstances change and the event needs to be cancelled. User 1 selects the event on Calendar 2 and deletes it. The event disappears from Calendar 2, and initially from Calendar 1, but reappears on Calendar 1 on the next browser reload and has to manually deleted from Calendar 2. I hope that makes senseā¦ Thanks, Romeyn -- signat-url: http://www2.potsdam.edu/prescor/signat-url.htm -- users@sogo.nu https://inverse.ca/sogo/lists
