Accepting an invitation to a changed event also returns MODIFICATION_FAILED, but this time the reply isn't sent. Debug logs:

I'm unable to reproduce the first error today, and didn't have server logging enabled yesterday, all I have is the access log which notes "POST /ucaldav/user/jamesa/Outbox/ HTTP/1.1" 500 1207 so I guess ignore that for now.

The second error is reproducible, the Bedework logs report edu.rpi.cct.webdav.servlet.shared.WebdavBadRequest: Mismatched names which happens even when the name of the event hasn't changed. Putting in some debugging shows Lightning is trying to PUT In-4b917b81-1c985cd5-011c98c81d84-000002f1.ics which is the .ics of the update in the CalDAV Inbox, but Bedework is expecting In-4b917b81-1c985cd5-011c98c73425-000002dd.ics which is the .ics of the event in the main calendar. Is this a bug in Bedework or Lightning?

Comment 3

[Andreas Treumann]

comment #1 bug is reproducible.

Accepting the event a second time after the organizer changed the start/endtime of the event leads to the modification failed error message.

error output:

Error: An error occurred when writing to the calendar Bedework - caluser2! Error code: MODIFICATION_FAILED. Description: 
Source File: file:///C:/Documents%20and%20Settings/at93795/Application%20Data/Thunderbird/Profiles/ulb7u3fd.shredder/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/modules/calUtils.jsm -> file:///C:/Documents%20and%20Settings/at93795/Application%20Data/Thunderbird/Profiles/ulb7u3fd.shredder/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/calendar-js/calCalendarManager.js

I checked this with a second caldav server (non bedework) and I got the same error message.

Comment 4

[Philipp Kewisch [:Fallen][📱📆]]

I don't have a bedework server available right now.

Which other servers have this problem?

Daniel, ludovic, any ideas on why this may happen?

Comment 5

[Kristian Kauper]

I think this is similar/identical to an issue I'm seeing. I'm using a Google Apps calendar via caldav. Everything appears to work ok (I can view/create events fine), but attempts to accept an invitation *always* fail with the MODIFICATION_FAILED message. I think a reply is sent to the meeting organiser, but the calendar event is *never* added to my calendar.

I'm using Thunderbird 3.0 Beta 3 and Lightning 1.0pre (nightly build 2009-08-20-05).

Console messages follow, but I'd say the most important one is:

"Cannot create/update events where you are not the organizer"

Full error console messages:

See Bug 511098.

[Philipp Kewisch [:Fallen][📱📆]]

Simon, any idea why this is happening? Can you reproduce?

Comment 8

[Simon Vaillancourt]

This bug seems to have the same root cause as bug 540398 (See my comment #6)

Comment 9

[Greg Johnson]

i have a fix for this in a thunderbird 3.1, lightning 1.0b2, horde kronolith H3 (2.3.4), jetty 6.1.22 environment, based on this post:
http://marc.info/?l=kronolith&m=121095297806530.

read/write sync works well by adding the following lines to /usr/local/share/horde/pear/php/HTTP/WebDAV/Server.php in the PUT switch statement:

case 'HTTP_CONTENT_TYPE': // defined on IIS and has the same value as CONTENT_TYPE
break;
                
case 'HTTP_CONTENT_LENGTH': // defined on IIS and has the same value as CONTENT_LENGTH
        break;


regards,
greg johnson

I've taken a look at this and the standard case works for me. The different organizer issue should be handled in bug 540410
