Miljenko Norsic [http://community.jboss.org/people/mnorsic] created the discussion "Problem with insertion of process instance into a knowledge session" To view the discussion, visit: http://community.jboss.org/message/629611#629611 -------------------------------------------------------------- Hi all, I have a small test process that uses persistency to store process and knowledge session data into a database.As part of my process workflow I have a Rule Task that pulls WorkflowProcessInstance from a knowledge session, and therefore I have to insert process instance into a ksession, as shown on picture: http://community.jboss.org/servlet/JiveServlet/showImage/2-629611-17071/s... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-629611-170... Upon signalEvent(), process continues, calls rule task and runs to completion, and there is nothing wrong with that. The problem is that my rule does not run: rule "Test WorkflowProcessInstance existence" ruleflow-group "test"     when         $p : WorkflowProcessInstance()     then         System.out.println("Process instance exists!"); end It is obvious that I'm missing WorkflowProcessInstance in a knowledge session, and therefore I've added it. But now I'm getting the following exception upon calling UserTransaction.commit() method: java.io.NotSerializableException: org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl$1 at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1164) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:330) ... It seems to me it is a bug in jBPM5.1, could someone please check it? If this is a bug, I can create a Jira issue, but since I'm a jBPM greenhorn, I'd rather like to check on forum first because maybe I'm missing something obvious ;) I'm attaching a sample Eclipse project with both persistent and non-persistent scenario.
