Hi,
(my current platform is Ganymede / CDO 2.0 (the latest version from the 2.0 maintenance branch) )
I have a model, and I commit it on CDO server, I can use this model in the current instance of my CDO server but when I restart the server and load my model,
I have this Exception :
org.eclipse.net4j.signal.RemoteException: java.lang.ClassCastException: org.eclipse.emf.ecore.impl.EGenericTypeImpl cannot be cast to org.eclipse.emf.ecore.EModelElement

I have set a breakpoint in MetaDataManager :
public EModelElement getMetaInstance(long id)
{
CDOIDMeta cdoid = CDOIDUtil.createMeta(id);
InternalEObject metaInstance = getPackageRegistry().getMetaInstanceMapper().lookupMetaInstance(cdoid);
return (EModelElement)metaInstance;
}
The value of metaInstance is org.eclipse.emf.ecore.impl.EGenericTypeImpl@1c03a0 (expression: XX)
I don't understand because I have not used a GenericType.
Regards,
Gaëtan.
