1197168 - changing an event's calendar does not work

Status: UNCONFIRMED

(Calendar :: General, defect)

Description

[Tilman Schmidt]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150812163655

Steps to reproduce:

0. Started Thunderbird with Lightning with two calendars configured:
- one local calendar named "Privat"
- one CalDAV calendar named "Fastmail"
1. Opened an ICS file "xing_event_1588682.ics" containing a single event. Lightning shows it as a separate calendar named "xing_event_1588682".
2. Opened the single event in calendar "xing_event_1588682" by double-clicking it. Edit Event dialog appears.
3. In the Edit Event dialog, changed the "Calendar" field from "xing_event_1588682" to "Fastmail" from the drop-down selection list.
4. Clicked "Save and Close".


Actual results:

Event is still in calendar "xing_event_1588682", as witnessed by:
- its colour still being the same
- when doubleclicked again, "Calendar" shows "xing_event_1588682"
- disappears when I unsubscribe from calendar "xing_event_1588682"


Expected results:

The event should be moved to calendar "Fastmail", ie.:
- its colour should change to the one assigned to calendar "Fastmail"
- when doubleclicked again, "Calendar" should now show "Fastmail"
- it should remain even if I unsubscribe from calendar "xing_event_1588682"

Do you get any messages in the error console (ctrl+shift+j)? Have you checked the CalDAV calendar is writable when trying this (as offline support is broken for CalDAV in 4.0.2 due to bug 1195974)?

Btw: you can import an event into a calendar directly by using the import functionality instead of opening as a calendar.

The error console had a lot of messages so I cleared it, repeated the test with a different event file, and got this message:

Yes, it is.

Interesting point. Offline support was enabled for that account.
Disabling it immediately after the above test made a _copy_ of the event appear in calendar "Fastmail".

Repeating the test with offline support disabled caused the "Fastmail" calendar to be disabled. The error console showed another entry like the above, followed by:

Timestamp: 21.08.2015 19:40:06
Warning: Error reading data for calendar: Fastmail. It was consequently set to write-protected mode because changes in this calendar will probably cause data loss. You can change this setting by selecting "edit calendar". Error code: DAV_PUT_ERROR. Description: An error occurred while storing the entry on the server.

After reenabling the calendar "Fastmail", it contained again a copy of the event.
