What could be the reason for no activation of any rule, when there should have been an activation for sure, because right object was inserted in the session and prior to that, rule parsing did not result in any error? Also, the audit log has this message, when that happens. <object-stream> <list> <org.drools.audit.event.ObjectLogEvent> <factId>1</factId> <objectToString>com.uhg.scs.optum.ng.hibernate.Person@31f2a7</objectToString> <type>1</type> </org.drools.audit.event.ObjectLogEvent> </list> </object-stream> -- View this message in context: http://www.nabble.com/No-activation-for-any-rule%21-tp20694737p20694737.html Sent from the drools - user mailing list archive at Nabble.com.
