[jboss-jira] [JBoss JIRA] Updated: (JBRULES-2957) Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@631b86c7" with two after-clauses

Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@631b86c7" with two after-clauses --------------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2957 URL: https://issues.jboss.org/browse/JBRULES-2957 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (fusion) Affects Versions: 5.1.1.FINAL Environment: macosx snowleopard jdk 1.6.x Reporter: Armin Steudte Assignee: Mark Proctor Attachments: TestProject.zip I'm getting the following Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@631b86c7" with one off my rules in my project. The problem is linked with the use of two after statements in one rule. If I delete one of them everything works like a charm. The rule looks like this: // Regeln rule "Vergessene Herdplatte" when // Platte wurde eingeschaltet und es steht kein Topf auf ihr $platte: HerdplatteEingeschaltet( plateOccupied == false ) from entry-point events // und in den nächsten 20 sek wird die gleiche Platte nicht ausgeschaltet not( HerdplatteAusgeschaltet( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) // oder es wird in den nächsten 20 sek kein Topf auf die Platte gestellt not( TopfAufHerdplatte( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) then System.out.println("Vergessene Herdplatte erkannt!"); end If I comment one of the not-clause out, it works. I created an unit-test which reproduces the exception. And here the Failure Trace: org.drools.RuntimeDroolsException: Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@631b86c7 at org.drools.common.AbstractWorkingMemory.executeQueuedActions(AbstractWorkingMemory.java:1473) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:182) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:145) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:96) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:44) at com.sample.FusionTest.testRule(FusionTest.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.BlockJUnit4ClassRunner.runNotIgnored(BlockJUnit4ClassRunner.java:79) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:71) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:49) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.lang.NullPointerException at org.drools.time.impl.CompositeMaxDurationTimer.createTrigger(CompositeMaxDurationTimer.java:58) at org.drools.common.Scheduler.scheduleAgendaItem(Scheduler.java:55) at org.drools.common.DefaultAgenda.scheduleItem(DefaultAgenda.java:314) at org.drools.reteoo.RuleTerminalNode.assertLeftTuple(RuleTerminalNode.java:185) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:189) at org.drools.reteoo.SingleLeftTupleSinkAdapter.propagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:78) at org.drools.reteoo.NotNode.assertLeftTuple(NotNode.java:101) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:189) at org.drools.reteoo.SingleLeftTupleSinkAdapter.propagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:78) at org.drools.reteoo.NotNode.assertLeftTuple(NotNode.java:101) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:189) at org.drools.reteoo.SingleLeftTupleSinkAdapter.propagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:64) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:128) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) at org.drools.reteoo.PropagationQueuingNode$AssertAction.execute(PropagationQueuingNode.java:347) at org.drools.reteoo.PropagationQueuingNode.propagateActions(PropagationQueuingNode.java:229) at org.drools.reteoo.PropagationQueuingNode$PropagateAction.execute(PropagationQueuingNode.java:443) at org.drools.common.AbstractWorkingMemory.executeQueuedActions(AbstractWorkingMemory.java:1471) ... 29 more
