Hi Martin,

I'm testing to migrate a Teneo 1.0.1 application to CDO 3.0 backed by a HibernateStore

I have the following use case:

1. Load previously exported XMI into an XMIResource
2. Transfer XMIResource content to the CDOResource (backed by a HibernateStore)
3. Save CDOResource and so persist data into an empty database

This was working in the old application as well as when using CDO 3.0 and a DBStore. Using the HibernateStore, however, the
following exception is thrown while save is invoked:

Halting at a breakpoint in CDOIDPropertySetter at line 77 I could verify that the object being processed ('Systemattributes') is
using a syntetic id. Could this be a problem?

I attach an zip with the configuration, logs with hbm mapping and stacktraces and the xmi I used.in case this could be of any help


Thanks in advanced!
