CDO Adding a new resource [message #422909] Thu, 18 September 2008 14:21 Go to next message

Hi guys,

Running a CDO server (version 2.0.0 stable build: ,200809110653) I can
now get our client app to connect and disconnect from the server. I can
also add containered objects without a hitch. However, I keep getting
an error when trying to add a new object that is not containered and
thus needs its own resource.

This is the code I use for the commit operation, where eObject is the
newly created object passed into the method:

if (eObject != null && eObject.eContainingFeature() == null &&
eObject.eResource() == null)
{
/* Object is not a contained feature */
//Create resource
URI newUri = URI.createURI("cdo:/" + getRepositoryName() + "/TEST");
Resource resource = transaction.getOrCreateResource(newUri.path());

if (resource.getContents().isEmpty())
resource.getContents().add(eObject);

for (Resource res : transaction.getResourceSet().getResources())
System.out.println("Resource in resourceSet: " + res + " URI: "
+ res.getURI());

}

if (transaction.isDirty())
transaction.commit();

I am able to confirm that the resource is successfully added to the
resource set:
Resource in resourceSet: CDOResource@OID7 URI:
cdo://1ff5d226-b1f0-40fb-aba2-0c31b38c764f/ISSE/CDO3
Resource in resourceSet: CDOResource@oid1 URI:
cdo://1ff5d226-b1f0-40fb-aba2-0c31b38c764f/ISSE/TEST

yet I get the following exception:

class org.eclipse.net4j.util.ImplementationError
Message:Missing ID mapping for oid1

org.eclipse.emf.cdo.internal.common.revision.CDORevisionImpl .remapID(CDORevisionImpl.java:800)

isse.netbeans.framework.IDENode.bridge.IDENodeAdapter.notify Changed(IDENodeAdapter.java:82)

Can anyone give me a pointer please. Oddly enough this was working in
CDO 1.0 so maybe I am missing something vital that is the difference
between the versions.

Hi PGR,

Which IStore implementation are you using for your repository? IIRC.
only today I saw some tests failing in the HibernateStore with the same
exception (but didn't come to it yet)...

Cheers

Eike,

Sorry, not totally certain what you mean by IStore. However, my topology
is a CDO server running standalone in an osgi session with a derby
database backend.

Not using Hibernate.

Hope that helps. Any more info or debugging required then let me know.

Regards

PGR

Yes, complete console dumps of client and server would be very helpful
to track down the problem.
Can you please attach them to a new Bugzilla?

Thx
