[rules-users] FAIL - getProcessInstances() from persisted StatefulKnowledgeSession
Hi everybody. 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 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@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
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.

Hi Stephan. Thank you for the replay. Next time I will read the javadoc before asking here.

Re: [rules-users] FAIL - getProcessInstances() from persisted StatefulKnowledgeSession
Actually, as far as I remember, getProcessInstances() from a restored session will ALWAYS return an empty list.
