Error description
The following exception is raised during an instance update instruction of a rule body Caused by : java.lang.NullPointerException in the conditions of rule 'xyz_rule_name', at offset 234, length 90 Caused by : java.lang.NullPointerException at com.ibm.rules.generated.ruleflow.tarification.prev_prado.RF_010_ PREV_PRADO$003etc.CondExecEnv.test31(Unknown Source) at com.ibm.rules.generated.ruleflow.tarification.prev_prado.RF_010_ PREV_PRADO$003etc.CondExecEnv.$sMethod$5(Unknown Source) at com.ibm.rules.generated.ruleflow.tarification.prev_prado.RF_010_ PREV_PRADO$003etc.CondExecEnv.evaluateBooleanMethodHook(Unknown Source) at com.ibm.rules.engine.rete.runtime.state.AbstractConditionExecEnv .evaluateBooleanMethod(AbstractConditionExecEnv.java:63) at com.ibm.rules.engine.rete.runtime.network.impl.IlrAbstractGenera torJoinNode.evaluateDiscTest(IlrAbstractGeneratorJoinNode.java:4 32) at com.ibm.rules.engine.rete.runtime.network.impl.IlrAbstractGenera torJoinNode.updateGeneratorElement(IlrAbstractGeneratorJoinNode. java:310) at com.ibm.rules.engine.rete.runtime.network.impl.IlrStandardWorkin gMemoryNode.updateGeneratorsElement(IlrStandardWorkingMemoryNode .java:78) at com.ibm.rules.engine.rete.runtime.network.impl.IlrStandardWorkin gMemoryNode.update(IlrStandardWorkingMemoryNode.java:69) at com.ibm.rules.engine.rete.runtime.AbstractReteEngine.updateInter nal(AbstractReteEngine.java:377) The issue is reproduced by the following reduced ruleset: rule ´p2.a3´ { ilog.rules.business_name = "a3" ilog.rules.dt = "" ilog.rules.package_name = "p2" status = "new" when { xom.A() from $EngineData.this.A; variable1 : xom.B(this.name != null) in $EngineData.this.A.listOfB; variable2 : xom.C(this.name.contains("a")) in variable1.listOfC; evaluate ( variable2.value >= 5); } then { ilog.rules.brl.System.printMessage((com.ibm.rules.engine.ruledef .runtime.RuleInstance.this.getRuleName() + "> ") + variable2.name); } } rule ´p2.a4´ { ilog.rules.business_name = "a4" ilog.rules.dt = "" ilog.rules.package_name = "p2" status = "new" when { xom.A() from $EngineData.this.A; ´the b´ : xom.B() in $EngineData.this.A.listOfB; ´the c´ : xom.C() in ´the b´.listOfC; evaluate ( ! xom.Utils.´exists´(´the b´.name)); } then { ´the c´.value = 0; ilog.rules.brl.System.printMessage((com.ibm.rules.engine.ruledef .runtime.RuleInstance.this.getRuleName() + "> ") + ´the c´.name); update (´the c´); } } The graph of instance that leads to the NPE is set to: a: A ( listOfB: [b] ) b: B ( name: null, listOfC: [c] ) c: C ( name: null )
