Hi all,
Im developing using drools version 5.0.0.M5. My application uses a stateless
session. I tried to assign an AgendaEventListener to the session, but failed
with a NPE.
This is my code structure:
KnowledgeBase kb =...;
StatelessKnowledgeSession session = kb.newStatelessKnowledgeSession();
session.getAgendaEventListeners().add(new DebugAgendaEventListener());
==>NPE!
java.lang.NullPointerException
at
org.drools.impl.StatelessKnowledgeSessionImpl.getAgendaEventListeners(StatelessKnowledgeSessionImpl.java:123)
Am I doing something wrong, or is it an error in drools?
no, it's a bug and fixed in trunk.
Thanks, David
