Re: [rules-users] Apply role to whole class hierarchy

Thanks for your help, Edson! We are using drools 5.4.0.Final via maven. Maybe I am missing something, so here's a quick overview of what we do. We have a model class ButtonEvent which is derived like this: ButtonEvent -> ZonedEvent -> VSCPEvent Then there's a rulebase with something like this: import test.vscp.VSCPEvent; import test.vscp.information.ButtonEvent; declare VSCPEvent @role( event ) @timestamp( timestamp ) @expires( 1h ) end declare ButtonEvent @role( event ) @timestamp( timestamp ) @expires( 1h ) end rule "Button long pressed" when b : ButtonEvent( action == Action.PRESSED ) not( ButtonEvent( action == Action.RELEASED, this after[0s,1s] b ) ) then ... end What I would have expected is that the second 'declare' statement to be unnecessary. However, if I take it away, this is what I get: java.lang.ClassCastException: org.drools.common.DefaultFactHandle at org.drools.base.evaluators.AfterEvaluatorDefinition$AfterEvaluator.evaluateCachedRight(AfterEvaluatorDefinition.java:316) at org.drools.rule.constraint.EvaluatorConstraint.isAllowedCachedRight(EvaluatorConstraint.java:80) at org.drools.common.SingleBetaConstraints.isAllowedCachedRight(SingleBetaConstraints.java:139) at org.drools.reteoo.NotNode.assertObject(NotNode.java:133) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:141) at org.drools.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:497) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:382) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:235) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:240) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:337) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:298) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:888) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:847) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:269) ...
