Hello,
i use CDO 2.0m4 with derby DB on Eclipse 3.5m4. Now i try to
upload/download some resources. And i get everytime this error:

[ERROR] Rollback in DBStore: org.eclipse.net4j.db.DBException: SQL
Exception: An attempt was made to get a data value of type 'VARCHAR'
from a data value of type
'org.eclipse.emf.cdo.internal.common.revision.CDOListImpl'.

Can somebody say what this exactly mean? I get often errors with cdo
2.0m4 has this version lots of errors or is derby not good to use for
the server?

Greetings

Jörg,

Currently I can't oversee if we had related fixes after M4. But we had
some fixes and I'm planning to publish a regular I-build later this
week. Is it possible that you try the same scenario with the latest
sources? If the problem persists please file a Bugzilla.

Cheers

Can you be a bit more specific on what you are trying to write? Maybe
describe your model and what values you set before committing?

Cheers,
Stefan

Hello,

i try to upload this model. Grounded on the rmof.ecore structure.
This is the code i use for

// Enable logging and tracing
OMPlatform.INSTANCE.setDebugging(true);
OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOL E);

// Prepare container
IManagedContainer container = ContainerUtil.createContainer();
Net4jUtil.prepareContainer(container); // Register Net4j factories
TCPUtil.prepareContainer(container); // Register TCP factories
CDOUtil.prepareContainer(container, false); // Register CDO factories
// container.activate();

// Create connector
connector = TCPUtil.getConnector(container, "localhost:2036");

// Create configuration
CDOSessionConfiguration configuration =
CDOUtil.createSessionConfiguration();
configuration.setConnector(connector);
configuration.setRepositoryName("repo1");

// Open session
session = configuration.openSession();
session.getPackageRegistry().putEPackage(RmofPackage.eINSTAN CE);

// Open transaction
CDOTransaction transaction = session.openTransaction();

// Get or create resource
String res = "/layer0";
// transaction.createResource(res);
CDOResource resource = transaction.getOrCreateResource(res);

//Adding the content
//...
resourcecopy.getContents().add(EcoreUtil.copy((EObject)
entry.getValue()));

// Work with the resource and commit the transaction
transaction.commit();
logger.debug("CDO commit");

session.close();
LifecycleUtil.deactivate(connector);

Thanks for your help.
Greetings

I tried it also in cdo 1.0.4 but there i get the following error:

SQL Exception: Lexical error at line 1, column 137. Encountered: "\\"
(92), after : "".

The nsURI is http:///rmof/rmof.ecore . Is this a bug?
