Hello Almo anonymous wrote : Are you referring to/calling another process inside the action handler? I am not referring or calling another process inside the action handler. The action handler's main job is to save the process instance.
anonymous wrote : Are you modifying another process definition inside your action handler No. My modification, I was referring to the process definition that have the action handler added each of it's transition. What I am trying to do is as processing at each node is completed, save the process instance so if the processing at next node fails, I can start rerunning from the same node where the failure occured. For the example process definition listed below, say if the processing at node 'second' fails, then I want to start reprocessing from state 'second'. I think I can justify why I was getting the exception (I may very well be wrong). I was saving process instance upon each transition. However, which node of the transition is associated with the token at that point is not clear to me. I think this is why the exception stating 'null' node. I modified to store process instance in a action handler that is executed upon node enter event. Now I am getting the following exception when I try to resume. org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: org.jbpm.graph.def.Node.leavingTransitions, no session or session was closed | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358) | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350) | at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:97) | at org.hibernate.collection.PersistentList.size(PersistentList.java:91) | at org.jbpm.graph.def.Node.getDefaultLeavingTransition(Node.java:189) | at org.jbpm.graph.exe.Token.signal(Token.java:89) | at org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:201) | at jpl.mipl.pgs.jbpm.JBPMExeEngine.execute(JBPMExeEngine.java:471) | at jpl.mipl.pgs.jbpm.JBPMExeEngine.main(JBPMExeEngine.java:531) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3918287#3918287 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3918287 ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
