We have a CDO server code that starts as an OSGI service.
The server code did not changed in recent times, but now we get the error below.
The only apparent thing we did is update our Eclipse 3.6 to the latest EMF projects versions (including CDO and Net4j).
Any suggestion?
Thanks

Hi Vincenzo,

I *suspect* that the code and the DB schema has changed in the meantime.
Can you try to export your model to XML, create a new
repository/store/DB and then import the model dump? Does that work?

Cheers

Hi Eike,
indeed, in order to avoid the problems you mention, we always drop the database before launching the CDO server (it's a prototype project and we've got populating JUnit tests).

However now the problem is just gone! Can't explain how.
Just updated some other EMF plugins, apparently.
Sorry for the false alarm.
Thank you Eike

Cheers
Vincenzo

No worries. Better it solved itself now than after a lot of effort being
spent on it :P
