(Calendar :: Lightning Only, defect)

Description

[allan k]

Attachment: ics file to be imported

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0
Build ID: 20120129141257

Steps to reproduce:

I am trying to migrate calendars from evolution to thunderbird (9) lightning (1.1.1) on ubuntu 11.10 (amd64)
Import fails.
I have now recreated problem exporting a 2 event test calendar. 
Attempted Import t1.ics (attached) to an empty local calendar.



Actual results:

Import appears to add the first event but the second (and subsequent in previous tests) fail.

Error console shows:
Warning: There has been an error reading data for calendar: BobC.  However, this error is believed to be minor, so the program will attempt to continue. Error code: DUPLICATE_ID. Description: ID already exists for addItem

Error: An error occurred when writing to the calendar BobC! Error code: MODIFICATION_FAILED. Description:

Line: 1108


Expected results:

Two events should have been added

[Stefan Sitter [:ssitter]]

This is a problem in your calendar. Each event must have a unique id (UID property). Events with the same UID are treaded as the same events.

So this looks like a bug in evolution export (saveas), could take an aeon to get fixed.
Is there a protocol for generating UID or could I just massage the current file with a script to add a suffix to each UID in ics?

Ignore last comment. I've noticed that evolution is generating correct number of events but they are all duplicates of the first entry, cleary not iterating through events. Should have spotted that sooner.
Close this one up.
