947138 - Events randomly not showing when offline mode support selected

Status: UNCONFIRMED

(Calendar :: Provider: CalDAV, defect)

Description

[Éric Würbel]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release)
Build ID: 20131115110315

Steps to reproduce:

When "offline mode support" is checked on a DAV calendar properties dialog, events randomly disappear. Sometimes they even never show up after their creation. Any kind of event can be affected (single events, periodic events , ...)

When offline mode support is unchecked, everything works fine. 

Firefox version 25.0.1 (canonical build for ubuntu system)

I can report a similar (same?) bug with
User agent: Mozilla/5.0 (Windows NT 5.1; rv:26.0) Gecko/20100101 Firefox/26.0 SeaMonkey/2.23
Build identifier: 20131210201652
using
Lightning 2.8b1

I use several CalDAV sources on an OwnCloud server. For months this used to be a very nicely stable setup. But in recent weeks, strange communication problems occurred. I had initially created the calendars with offline support ON. So I thought it a good idea to test whether this offline feature might have to do with it.

Turn offline support off: calendars keep working (as long as connected to the web)
Turn offline support on: all events and tasks are "gone" -- meaning they do not show in lightning anymore
Turn offline support back off: calendars are working again.

This is reproducible.

An annoying quirk that makes offline work that much more difficult.
