Re: [rules-users] Listen event in different package

Hello I am a beginner in Drools 5.1.1 and try to listen a event in a packageX inserted by a rule in another packageY. I have following 2 drl file : ---inserter.drl---- package packageY import internal.event.*; declare EventItem @role (event) end rule "insert EventItem" when ... then EventItem ei = new EventItem(...); insert(ei); end ---------------- ---listener.drl--- package packageX import internal.event.*; rule "listen EventItem temporal constraint" when ei: EventItem() oi: OtherItem(this after ei) then System.out.println("Hello word"); end ---------------- EventItem and OtherItem are defined in 'internal.event' package. If I run with a StatefulKnowledgeSession configured in 'pseudo clock', I have following stack trace: java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to org.drools.common.EventFactHandle at org.drools.base.evaluators.AfterEvaluatorDefinition$AfterEvaluator.evaluateCachedRight(AfterEvaluatorDefinition.java:322) at org.drools.rule.VariableRestriction.isAllowedCachedRight(VariableRestriction.java:117) at org.drools.rule.VariableConstraint.isAllowedCachedRight(VariableConstraint.java:121) at org.drools.common.SingleBetaConstraints.isAllowedCachedRight(SingleBetaConstraints.java:151) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:125) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:145) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:190) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:145) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1174) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1123) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:917) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:251) ... Moving listener.drl in packageY, all works. I don't know if it is already open a related issue, perhaps the : https://issues.jboss.org/browse/JBRULES-2774 Thanks for your attention. Regards.
