To view the discussion, visit: https://community.jboss.org/message/755169#755169 -------------------------------------------------------------- I create a ksession for every processinstance. The process instances are created without any problem.But when i  complete the task of the process instances. Im getting this exception javax.persistence.OptimisticLockException: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.drools.persistence.info.SessionInfo#1]           at org.hibernate.ejb.AbstractEntityManagerImpl.wrapStaleStateException(AbstractEntityManagerImpl.java:630)           at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:588) I understand that another thread is trying to access a row which is already deleted from the table after completing it. But I have to use multiple ksessions. How would i use those without getting this exception. I have attached the class files for reference. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/755169#755169] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
