from persisted StatefulKnowledgeSession</font></table>
<br>
<hr noshade>
<br>
<br>
<br><font size=3>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>
