[CDO] Transaction Exception [message #513552]

Wed, 10 February 2010 09:47

Eclipse User

All,

I am playing with the material given by Eike at Eclipse summit during the Advanced Programming Techniques with EMF and CDO.
I have a problem when creating a simple Root Eobject within a transaction:
CDOSession session = openSession();
session.getPackageRegistry().putEPackage(InventoryPackage.eI NSTANCE);
// open the transaction
CDOTransaction transaction = session.openTransaction();

// create the resource
CDOResource resource = transaction.getResource("/edine/resto2.inventory");
// Work with resource
Restaurant restaurant = InventoryFactory.eINSTANCE.createRestaurant();
resource.getContents().add(restaurant);

// Commit the transaction
transaction.commit();

session.close();

But I have got a TransactionException due to the "id instanceof CDOIDTemp".
Have you got any idea ?

The exception is:
Exception in thread "main" org.eclipse.net4j.util.transaction.TransactionException: Rollback in DBStore: java.lang.IllegalArgumentException: id instanceof CDOIDTemp

putEPackage() shouldn't be necessary.

Shouldn't that be createResource()?

I admit that te exception message is not very convenient :P

Which exact version of CDO are you using?

Hi Eike,
In the plug-in detail I found:
Plug-in version 3.0.0.v2009XX. for all CDO plug-ins. The same for CDO features all pre-fixed by 3.0.0.
Actually I re-use the Eclipse version I got from the Eclipse Summit workshop.
Do you need more information ?

Thanx !

Sabri.

Have you followed my advice to use createResource() instead of
getResource()?

Cheers

Actually I tried with a createResource(), with the getorCreateResource() and I have even tried with creating a resource with the CDO client UI. But even with the last try, I managed to create the resource with the client UI, and From my client code, I manage to get it but always the same exception on commit.

BTW, for a production or prototype do you advise to use CDO 3.0 or 2.0 ?

For production 2.0 latest (builds to be provided soon again)
For prototyping 3.0 latest.

Eike,

I have tried by creating a transaction with the CDO UI Client. The creation of an empty resource works, but if I try to create something within this resource it fails when I commit with this same strange exception. The same if I try from a client Transaction API.

Therefore, I downloaded all the CDO 3.0 sources from repository and I re-test the same use case, it fails with the same exception.

Have you got any idea ?

Thank you,

Sabri.

Can you send me a zip with a test case or a Java program that I can use
to reproduce the problem?

Hi Sabri,

I've played with the zips you sent. There's one obvious bug in your
model plugin.xml. The referenced package class does not exist because
you added a package base prefix. Fixing that should enable you to import
the XML file. But you're right, there seems to be a regression in the
DBStore that causes temporary meta IDs not being remapped after
successful commits. Please file a bugzilla.

If you want to go ahead, please try out the MEMStore instead of the DBStore:

IStore store = MEMStoreUtil.createMEMStore();

Cheers
/Eike

OK thanks ! By replacing the DB store it works indeed.
I will fill in a bugzilla.

thanks for the support.
