parent process

Description of problem:
When a signal is expected in a subprocess it is ignored.

How to reproduce:
(using the attached processes)
1) start a process in jbpm5
2) signal it ("Continue" signal) in jbpm6.

Expected result:
Both process instances (parent and child) will be COMPLETED

Actual results:
Both process instances are in ACTIVE state

Note:
I found that when I access the process instances before the signal is made all is fine

KieSession ksession = restoreKnowledgeSession(sinfo.getSessionId(), "BPMN2-CallActivity.bpmn2", "BPMN2-CallActivitySubProcess.bpmn2");

for (Long pid : sinfo.getProcessInstanceIds()) {
    System.out.println("Instance: " + pid + ", State: " +     ksession.getProcessInstance(pid));
}
ksession.signalEvent("Continue", null);
ksession.dispose();
