1022655 - Event is giving an error message when attempting to be accepted/declined in Thunderbird, despite not being touched on the server: "This item has recently been changed on the server. Submitting your change will overwrite the changes made on the server."

Status: RESOLVED INCOMPLETE

(Calendar :: General, defect)

Attachment: Lightning Error Message.png

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36

Steps to reproduce:

OS X 10.9
Thunderbird v 24.5.0
Lightning (latest version)
CalDav: Oracle Communications Calendar Server version: 7.0.4.14.0
Calendar has over 11900 events

Event was attempted to be accepted in Thunderbird Lightning.

If you would like to work directly with the customer experiencing this issue, please contact us and we will pass on his information.


Actual results:

When clicking Accept, the event gives an error message: "This item has recently been changed on the server. Submitting your change will overwrite the changes made on the server." It gives two options: "Discard my changes" or "Submit my changes anyway." The event was not changed or event viewed on the server. Neither option allows the event to be accepted and the pop up either returns or does not go away. 


Expected results:

The event should either accept or discard the change, per action taken, or not appear at all if the event was not changed on the server.

Does the problem still exists using the current Lightning 3.3 release with Thunderbird 31?

The message might be triggered by CalDAV calendar or by Cache calendar:

Have you enabled offline cache for your calendars? If yes, does the problem still exists after switching off the offline cache? If yes, does it still exist after removing file "calendar-data/cache.sqlite" in your profile folder and re-enabling the offline cache?
