[jboss-user] [jBPM] - ClassCastException in DynamicUtils when using JPAKnowledgeService.loadStatefulKnowledgeSession()

Wooi Joe Chuah [https://community.jboss.org/people/joe.chuah] created the discussion "ClassCastException in DynamicUtils when using JPAKnowledgeService.loadStatefulKnowledgeSession()" To view the discussion, visit: https://community.jboss.org/message/779244#779244 -------------------------------------------------------------- Hi, I've encountered the problem as stated above when using DynamicUtils to addDynamicSubProcess at the following line ProcessEventSupport eventSupport = ((InternalProcessRuntime)((InternalKnowledgeRuntime)ksession).getProcessRuntime()).getProcessEventSupport(); The reason as far as I know is because the ksession returned from JPAKnowledgeService.loadStatefulKnowledgeSession() or newStatefulKnowledgeSession() which is implemented using org.drools.persistence.jpa.KnowledgeStoreServiceImpl returns the ksession as a CommandBasedStatefulKnowledgeSession object instance. The CommandBasedStatefulKnowledgeSession does not implement InternalKnowledgeRuntime and hence we hit a class cast exception. The same problem does not occur when using a ksession from the KnowledgeBuilder>KnowledgeBase>ksession. Any idea if CommandBasedStatefulKnowledgeSession is going to implement InternalKnowledgeRuntime in the future or there's gonna be a fix for using sessions which are loaded from DB? or is it a limitation Thanks. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779244#779244] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
