The question is that I want to create a new ProcessInstance inside an outer ProcessInstance, actually this creation (new) operation is done in the ActionHandler of the outer ProcessInstance, the key is that the outer one is a persisted one, but I don't want the inner one to be persisted. So I got the following exception when I try to close the jbpmContext: anonymous wrote : org.hibernate.TransientObjectException: object references an unsaved transient instance - save the t | ransient instance before flushing: org.jbpm.graph.def.Node | at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:219) | at org.hibernate.type.EntityType.getIdentifier(EntityType.java:397) | at org.hibernate.type.ManyToOneType.isDirty(ManyToOneType.java:242) | at org.hibernate.type.TypeFactory.findDirty(TypeFactory.java:597) | at org.hibernate.persister.entity.AbstractEntityPersister.findDirty(AbstractEntityPersister. | java:3128) The code is as below: The outer one: | JbpmContext jbpmContext = JbpmConfingurationFactory.jbpmConfiguration | .createJbpmContext(); | try { | ... | ProcessInstance processInstance = new ProcessInstance(retrievedPd); | jbpmContext.save(processInstance); | } | } finally { | jbpmContext.close(); //where I get the exception | } | | One ActionHandler of the outer one which expect to create a new ProcessInstance: | public void execute(ExecutionContext executionContext) throws Exception { | // get operation context from workflow | OperationContext context = (OperationContext) executionContext | .getContextInstance().getTransientVariable( | Operation.OPERATION_CONTEXT); | // create discovery operation | WorkflowOperation discoveryOperation = new WorkflowOperation(context); | // create discovery related workflow | ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(definition); | ProcessInstance processInstance = | new ProcessInstance(processDefinition); | .... | Can anybody tell me why I got this error, is there any possible workaround?
