Some people reported problems with TB3.1.x and SOGo Extensions so I tried TB3.0.x but the same problem.

Which version of SOGo?

Also, is Funambol running on the same server as the SOGo server?

SOGo: Latest nightly RPM packages. I update every 1-2 days.
Funambol: Official recommended 8.5.2

Yes, Funambol runs on the same server as SOGo.

Great, I seems to work again.

The only thing I did was updating to the latest nightlies.

You can close this bug. Thx a lot.

I must correct myself. It isn't solved :(

But I have more details.

This problem occurs only if you create an event on your mobile, sync it, edit it in thunderbird and sync back to mobile (until that point all is good and the edited event is shown correctly) but if you than edit the event again on your mobile and resync the changes are only shown in webinterface and not in thunderbird!

The problem doesn't seem to occur if you create the event on your mobile and make all changes to the event on your mobile. Then the changes are shown correctly in thunderbird and webinterface.

So the edit through thunderbird seems to be the problem.

One addition:

These problems only occur with Lightning Invers. If I use Lightning STD without the SOGo extensions all works as it should.

Maybe some kind of caching problem as Lightning Invers enforces caching?

No ideas?

If this problem is really a caching problem of Lightning Invers only could an administrator please change the category appropriately?

Yesterday I was able to reproduce the issue (but not find the root cause of it) and today all is working well.

It would be nice to find a precise test case that makes this fail repetitively.

Ok, I tried a few scenarios and found such a reproducable event.

Remark:
In every step I reload all calendars to get changes/new events!
In every step I changed the subject "test +counter{1,2,3...}" and the location.

What I did:
1.) Created event without reminder (!!! ) on mobile phone and synced it. -> Changes are seen in webinterface and thunderbird
2.) Changed event in thunderbird. -> Changes are seen on mobile phone.
3.) Changed again on mobile. -> Changes are seen in thunderbird and webinterface.

Now the interesting part:
4.) Added an reminder (!) on mobile and changed event's title. -> Event is correct in webinterface (except the reminder but this is a known problem of absolut vs. relativ time conversion) but NOT in thunderbird.

I can reload thunderbird as often as I want but it remains the old title and not the changed one!
I have to close thunderbird, delete "cache.sqlite" in the profile's directory and restart thunderbird to get the changes.

I can't grok this.

"Event is correct in webinterface (except the reminder but this is a known problem of absolut vs. relativ time conversion) but NOT in firefox.
I can reload firefox as often as I want but it remains the old title and not the changed one!"

Do you mean Thunderbird instead of "firefox" ?

My mistake: of course I mean thunderbird instead of firefox.

I updated the description in 0001886.

Do you now understand what I mean or should I try to describe it more detailed?

Any news on this? I have the same problem, exactly the same with BB sync

No, nothing new. I'm waiting for a reply of ludovic.
