Description

[KitchM]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.10) Gecko/20100916 Firefox/3.6.10

Import of .ics file results in "An error has occurred" message, and a MODIFICATION_FAILED message.

Reproducible: Always

Steps to Reproduce:
1.Try to import .ics file.
2.
3.
Actual Results:  
It appears that the information is actually imported, but I cannot be sure.

Expected Results:  
No errors.

This is one of those situations where it is extremely difficult to trust the integrity of data in and around Thunderbird, as has been noted in other reports.  Something is possibly happening with the information from the file but the user can't be sure.

Can you attach a ics file that can be used to reproduce the problem? Is the ics file valid? Does it pass the iCalendar Validator <http://severinghaus.org/projects/icv/>?

If the problems occurs again please check Tools > Error Console. Hopefully the real error message is reported there. If yes please copy+paste them here.

IIRC I got this error message while I tried to import the same ICS file for a second time.

btw: Duplicate of bug 557312?

No response from reporter. Resolving incomplete until requested information is provided.

Larsen, importing an event a second time is not possible (bug 325449). You can identify this error by looking at Error Console. It will show a message similar to "Error code: DUPLICATE_ID. Description: ID already exists for addItem".

At work, I'm using Sunbird (1.0b1) (using outlook for email).
At home, I'm using the latest firebird/lightning.
When I have an updated event at home, I would export calendar at home, email ICS to work, delete the calendar at work, and import the ICS - all these just for one updated event.
It really would be nice if import will look at the last modified date to decide whether it is an error or whether it should just be replaced.

Using Windows 8.1 + Thunderbird 24.6 + Lightning 2.6.6, when import a .ics files, nothing happens.

Sometimes, with only one event, i got MODIFICATION_FAILED erro.

I´ve passed .ics file thought http://severinghaus.org/projects/icv/ with a "Congratulations; your calendar validated!".

Any way to fixit ?

Same problem, Windows 7, Thunderbird 38.7.2, Lightning 4.0.7.2. The .ics did validate with http://severinghaus.org/projects/icv/. Would love to post Error Console as requested, but I see no way to copy or save it. Here is a screen shot: http://www.novatec-inc.com/pub/ErrorConsole.jpg

Messages from error console can be copied using context menu that is available after right click.

First messages states that an event with the same unique identifier already exists in the target calendar. Two events with the same unique identifier are not allowed, therefore import is aborted. To improve this specific situation Bug 325449 was filed.

The two last messages are just an error while trying to report the original error and will be fixed with Bug 1260768.

> Two events with the same unique identifier are not allowed, therefore import is aborted.

When you say, "import is aborted", does that mean that importing actually stops at that point and no further entries are imported? So, I'm likely missing events?

Right-clicking on an Error Console entry does let me copy that single entry. Is that the best I can do? I cannot select/copy all entries at once?

The original ICS file was from Outlook 2010.
