Re: [rules-users] FAIL - getProcessInstances() from persisted StatefulKnowledgeSession

Hi, see javadoc of org.drools.runtime.process.ProcessRuntime.getProcessInstances(): * Returns a collection of currently active process instances. Note that only process * instances that are currently loaded and active inside the engine will be returned. * When using persistence, it is likely not all running process instances will be loaded * as their state will be stored persistently. It is recommended not to use this * method to collect information about the state of your process instances but to use * a history log for that purpose. If no instance is loaded yet, that this behaviour is exactly as described. Mit freundlichen Grüssen/Best regards i. A.

I configured the session persistence and persisted an instantiated process. When I get the session from the database and use the method getProcessInstances(), it returns an empty collection. But, when I call getProcessInstance(1), and 1 is the InstanceId of the ProcessInstanceInfo (table that contains the process instance), I get the correct process instance. Is this a bug? See the code below. statefulSession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, knowledgeBase, null, environment); Collation<ProcessInstance> processInstances = statefulSession.getProcessInstances(); // FAIL - return empty collection ProcessInstance processInstance = statefulSession.getProcessInstance(1); // OK - return the process instance Regards, Anderson_______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
