Using Correlations in JBPM-BPEL
Hi,
I assume I can post queries regarding JBPM-BPEL here.
I am using jBPM-BPEL 1.1.GA with JBOSS 4.2.0.GA. I am having correlation sets in my process. But I am not able to deploy the process. Deployment throws a hibernate exception
org.jbpm.JbpmException: problem closing services {persistence=org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.ibm.wsdl.MessageImpl}
org.jbpm.svc.Services.close(Services.java:245)
org.jbpm.JbpmContext.close(JbpmContext.java:139)
org.jbpm.bpel.web.DeploymentServlet.deployProcessDefinition(DeploymentServlet.java:195)
root cause
org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.ibm.wsdl.MessageImpl
org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:219)
This happens only when I use correlation sets. If I remove the reference to the correlation sets, it works fine and gets deployed. Any idea how to solve this? has anyone come across such an error? I googled and didn't find many answers
I am attaching the bpel and wsdl files here

Is there any document explaining the usage of correlation sets in Jboss jbpm bpel?
