Hi Stephan.<br><br>Thank you for the replay. Next time I will read the javadoc before asking here.<br><br>Regards,<br>Anderson<br><br>2011/3/30 <<a href="mailto:Stephan.Koops@we4it.com" target="_blank">Stephan.Koops@we4it.com</a>><div>

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

> Date: 30.03.2011 05:34<br>> Subject: [rules-users] FAIL - getProcessInstances() from persisted StatefulKnowledgeSession<br>> ________________________________<br>><br>><br>> Hi everybody.<br>><br>
> 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.<br>
><br>> statefulSession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, knowledgeBase, null, environment);<br>><br>> Collation<ProcessInstance> processInstances = statefulSession.getProcessInstances(); // FAIL - return empty collection<br>
><br>> ProcessInstance processInstance = statefulSession.getProcessInstance(1); // OK - return the process instance<br>><br>><br>> Regards,<br>> Anderson_______________________________________________<br>
