[CDO] CDOIDUtil.read - Illegal type: OBJECT [message #1048365]

Hi,

I can't specify when it occurs and I can't provide a unit-test. After doing some modifactions, I finally add an item to a list (which does not contain the item, it's contained somewhere else).

After doing the commit I get the exception:

I am using the current trunk of CDO and everything is running in one Java instance.

If I remove the 'add' to the list, there is no exception.

Can somebody give me a clue, what's wrong or how I can debug the problem?

Regards,

Per Sterner

Hi Per,

Are you sure that you're using the same CDO version on both clients and server?

Cheers

Yes, I am really running in one Java-VM (the current CDO and net4j plugins from trunk are in my workspace). I have debugged a lot and it appears, that:

0. transaction.commit(); // I commit my changes
[...]
1. CDODataOutputImpl.writeCDOLockState is called and the lockedObject type is CDOID. It's instance is TransactionCommitContext$DeltaLockWrapper$ForID.
2. CDOUtil.write is called and id.getType(); return OBJECT as type and ordinal is 1

[...] Later on:

3. CommitTransactionRequest.confirmingNewLockStates is called
4. readInt() returns 1
5. in.readCDOLockState() is called
6. CDOIDUtil.read is called. ordinal is 1
6. type is OBJECT and causes the exception

You should check your run configuration as well, it may have mixed up installed plugins and workspace plugins.

I've indeed changed something (a lot) about the IDs:

I suggest that you submit a bugzilla and after the JAX conference I'll look at it. Please attach all the infos you've
given here and that may help to reproduce the problem in a test case.

I noticed that the Legacy Mode is now the preferred option? (http://wiki.eclipse.org/CDO_Legacy_Mode)

I managed to test against 'emf-cdo-I20130418-0209-Site'. (I had some problems because of EMF v2.7 and the 'MinimalEStoreEObjectImpl' retrofit bundle. My Model-Bundle couldn't resolve the class 'MinimalEStoreEObjectImpl')
After adjusting my old genmodel file to use 'EObject' it works with the retrofit bundle Smile

Finally, the exception occurs..

Hmm, I wouldn't say so. Now there is no explicit legacy *mode* anymore, or you could say it's always on. But that
doesn't mean that all objects should now be legacy objects. It's just that they're always supported and that there's no
way to exclude them by configuration of the CDOView.

If you have the chance to regenerate your model for CDO I strongly recommend to do it!

Similar problems have been reported already and we think that bugs in PDE cause them. At runtime all seems okay with our
retrofit fragment. Does it make a difference for you whether you deploy the retrofit fragment in binary form to the
target platform or in source form to your workspace?

> After adjusting my old genmodel file to use 'EObject' it works with the retrofit bundle :)
Well, in that case the retrofit fragment is not needed at all because your objects are legacy objects (with all their
disadvantages).

Okay, I adjusted my genmodel.

I just tried it and it doesn't work for me in any configuration.

I created some testbundles (not related to anything) and there the same problem occurs. I looked into the section "Plug-In Dependencies" and the fragment doesn't appear there. But if I choose "system.bundle" as host-bundle it appears in the "Plug-In Dependencies" section and it works. But this doesn't really help Confused

My workaround for now is to manually add the MinimalEStoreEObjectImpl class to the org.eclipse.emf.cdo, so it's directly visible. Otherwise my model bundle isn't compiled.
