It seems like the state of the clone isn't set to OFFLINE when connection is lost.. Therefore an exception occurs. After this exception the state changes to OFFLINE but this is too late (or the commit/save should be done again).

I plan to spend some time on testing the offline replication mechanism. Hopefully by end of this week. But I can not
promise it 100%.


Eike, any progress on this?

No, I'm sorry! And it seems more and more unlikely that I manage to get at this before end of the EclipseCon next week.
Still these possible issues with the offline mode are very high on my list.

Cheers

I'm curious if you already had the time for this issue?

Yes. I have been distracted for a couple days, though.

I really appreciate the effort you put into this! The result is amazing and we're definitely going to use this in our applications.

Eike,

We found a problem in the 'org.eclipse.emf.cdo.server.db' plugin. In a few classes, for example 'AbstractHorizontalMappingStrategy', double quotes were added to the table alias. We've tested it with MySQL version 5.5.25, but it doesn't work because of these quotes.. the MySQL syntax won't accept it. When I remove the quotes, everything works fine again. But you must have added them for a reason, because they weren't there in the previous version..

Regards,
Ricky de Klerck

That has been reverted already. Please use a newer drop. If the problem is still there, please submit a bugzilla and
tell us exactly where you've found the quotes.
