Hi,
at some point in my application I reload my session:
JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, config, env);
then my process instance:
WorkflowProcessInstance processInstance = (WorkflowProcessInstance) ksession.getProcessInstance(processInstanceId);
and then try to set a process variable:
processInstance.setVariable(name, value)
which fails :
java.lang.NullPointerException
at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:68)
at org.jbpm.process.instance.impl.ProcessInstanceImpl.getContextInstance(ProcessInstanceImpl.java:133)
at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setVariable(WorkflowProcessInstanceImpl.java:238)
...
The reason is: the variable InternalKnowledgeRuntime kruntime in ProcessInstanceImpl is null.
Is it a bug or is there another way to load the process instance?
Regards,
Oleg
