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.

[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<ProcessInstance> processInstances =
statefulSession.getProcessInstances(); // FAIL - return empty collection
ProcessInstance processInstance = statefulSession.getProcessInstance(1);
// OK - return the process instance
