Rules Fact Error In Complex Condition Structure ----------------------------------------------- Key: JBRULES-2045 URL: https://jira.jboss.org/jira/browse/JBRULES-2045 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 4.0.6 Reporter: Hao Chen Assignee: Mark Proctor We are running into a complex production rule that either doesn't work or generate errors. I debugged and it seems Drools is not using the correct fact for some segments of the rule conditions. Steps to reproduce 1. Build the attached test case 2. Run the DroolsDefectTest junit test, it should print value "Worked!" on the output console. 3. Modify the rule by remove the commented condition that uses variable b2. 4. Run the test again. Expected result: the rule should output "Worked!" again. Actual result: failed with error: org.drools.RuntimeDroolsException: org.drools.test.Rule_test_0Eval4Invoker@68f1f17a : java.lang.NumberFormatException: For input string: "Y" at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:82) at org.drools.reteoo.EvalConditionNode.assertTuple(EvalConditionNode.java:148) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple(SingleTupleSinkAdapter.java:20) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:156) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:318) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:145) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:299) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:162) at org.drools.reteoo.Rete.assertObject(Rete.java:175) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory.doInsert(ReteooWorkingMemory.java:71) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:915) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:887) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:688) at com.firstbest.rules.DroolsDefectTest.test_drools(DroolsDefectTest.java:35) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at junit.framework.TestCase.runTest(TestCase.java:154) at junit.framework.TestCase.runBare(TestCase.java:127) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Caused by: java.lang.NumberFormatException: For input string: "Y" at java.lang.NumberFormatException.forInputString(Unknown Source) at java.lang.Integer.parseInt(Unknown Source) at java.lang.Integer.valueOf(Unknown Source) at com.firstbest.rules.Field.intValue(Field.java:29) at org.drools.test.Rule_test_0.eval4(Rule_test_0.java:32) at org.drools.test.Rule_test_0Eval4Invoker.evaluate(Rule_test_0Eval4Invoker.java:20) at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:77) ... 32 more -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
