Once the process goes into waiting mode and is woken up by a Message event like a Boundary Message, how will the Object A work. How will it Wed, 10 Feb 2016 15:55:07 GMT https://connect.hyland.com/t5/alfresco-archive/question-about-how-the-jpa-persisted-process-variable-object/m-p/211998#M165128 muralimohan123 2016-02-10T15:55:07Z Re: Question about how the JPA Persisted Process Variable Object works in a BoundaryMessage event https://connect.hyland.com/t5/alfresco-archive/question-about-how-the-jpa-persisted-process-variable-object/m-p/211999#M165129 <HTML><HEAD></HEAD><BODY><SPAN>Activiti only stores the reference to the id, and then uses the Hibernate entityManager to ressurect it.</SPAN><BR /><SPAN>It would help a lot if you can craft us a simple unit test that demonstrates this problem, so we can troubleshoot and fix it.</SPAN></BODY></HTML> Thu, 11 Feb 2016 09:53:51 GMT https://connect.hyland.com/t5/alfresco-archive/question-about-how-the-jpa-persisted-process-variable-object/m-p/211999#M165129 jbarrez 2016-02-11T09:53:51Z Re: Question about how the JPA Persisted Process Variable Object works in a BoundaryMessage event https://connect.hyland.com/t5/alfresco-archive/question-about-how-the-jpa-persisted-process-variable-object/m-p/212000#M165130 <HTML><HEAD></HEAD><BODY><SPAN>I have some more information. This is happening in a situation where there are 3 levels of processes - Process 1 calling Process 2, which calls Process 3. Or in other words, Process 3 is a sub process of Process 2 and Process 2 is a sub process of Process 1.</SPAN><BR /><BR /><SPAN>On querying Activiti tables, I see that the relevant Object appears as a jpa_entity along with the id in TEXT2_ in Process 1 and Process2. But in Process 3, it is a serializable and has null ID. it is in Process 3  that the Session closed issue happens. Why is the Process 3 considering the Object a Serilaizable and not a jpa-entity is a mystery. Any ideas?
