Hello,

I'm trying to save a model into the CDO.
Unfortunately I get on client side a NPE:
Caused by: java.lang.NullPointerException
	at org.eclipse.emf.cdo.server.internal.net4j.protocol.CommitTransactionIndication.indicatingCommit(CommitTransactionIndication.java:182)
	at org.eclipse.emf.cdo.server.internal.net4j.protocol.CommitTransactionIndication.indicating(CommitTransactionIndication.java:99)
	at org.eclipse.emf.cdo.server.internal.net4j.protocol.CDOServerIndicationWithMonitoring.indicating(CDOServerIndicationWithMonitoring.java:110)

	at org.eclipse.net4j.signal.Signal.doInput(Signal.java:328)

	at org.eclipse.net4j.signal.IndicationWithMonitoring.execute(IndicationWithMonitoring.java:66)
	at org.eclipse.net4j.signal.Signal.runSync(Signal.java:253)

and on server side the console show me tons of the following error:
!ENTRY org.eclipse.net4j.util 4 0 2014-11-12 16:04:38.664
!MESSAGE Invalid signalID 19456

        at org.eclipse.net4j.util.concurrent.Worker$WorkerThread.run(Worker.java:206)

I can reproduce the issue the with CDO Explorer and when I commit the session by my own code.
Any idea how to solve this issues or any hint for bug hunting?

Regards,
Johannes.

Hi Johannes,

Which release of CDO do you use?
Do you use the same release for server and client?

Best Regards.

Invalid signal IDs can have one of the following two causes:

1) Client and server do not use the same protocol implementation (same build!), or
2) A bug in the physical transport implementation, i.e. TCPConnector.

A bug in the CDOProtocol is very unlikely because the individual signals that go through an IChannel (e.g. the one that
connects a CDOSession to the server) are isolated against each other and the signal ID is not part of the
application-level protocol.

Hi Esteban and Eike,

thanks for your hints. The problem was differences in versions of client and server.
