This is the exception I got when I tried to send an event to an operation. The complete stacktrace of the application is

This error was because the Correlation Sets initiation property was set to Yes. If the initiation property of correlation set to Yes, it will create a new process instance with the correlation value if the receive is invoked. So I believe in our case WPS was trying to create a new process with the same id. That could be the reason for that TomDuplicateKeyException. Anyways this issue got resolved when I changed the initiation property value to join.

    I faced the same problem as you did, it was like you said
    It would take me a lot of time to guess that :)
    Thank you

    Where do we set it to Join? Is this via the WAS admin console or??

    It needs to be set in the properties window. The details are in the below post.
