[jboss-jira] [JBoss JIRA] (DROOLS-809) NPE when using extend rules with or node and exists

[ https://issues.jboss.org/browse/DROOLS-809?page=com.atlassian.jira.plugin... ] Mario Fusco resolved DROOLS-809. -------------------------------- Resolution: Cannot Reproduce Bug I'm not sure which commit fixed this issue (if any) but I couldn't reproduce that NPE on master. The test case I used to try to reproduce this problem (borrowed from the linked github project) follows: {code} @Test public void testExtendRuleWithOr() { // DROOLS-809 String drl = "import " + Customer.class.getCanonicalName() + "\n" + "import " + Car.class.getCanonicalName() + "\n" + "\n" + "rule \"base\"\n" + "when\n" + " (\n" + " (\n" + " $car := Car( $customer := customer )\n" + " and\n" + " exists Customer( this == $customer, age > 50 )\n" + " )\n" + " or\n" + " (\n" + " $car := Car( $customer := customer )\n" + " and\n" + " exists Customer( this == $customer, age > 30 )\n" + " )\n" + " )\n" + "then\n" + " System.out.println(\"rule\");\n" + " System.out.println($customer);\n" + " System.out.println($car);\n" + "end\n" + "\n" + "rule \"extended\" extends \"base\"\n" + "when\n" + " $car := Car( customer == $customer )\n" + "then\n" + " System.out.println(\"Extended rule\");\n" + " System.out.println($car);\n" + "end\n"; KieSession ksession = new KieHelper().addContent( drl, ResourceType.DRL ) .build() .newKieSession(); Customer c1 = new Customer( 85 ); Car car1 = new Car(c1); ksession.insert(c1); ksession.insert(car1); ksession.fireAllRules(); } public static class Car { public Customer customer; public Car(){ } public Car(Customer customer) { this.customer = customer; } public Customer getCustomer() { return customer; } public void setCustomer(Customer customer) { this.customer = customer; } } public static class Customer { int age; double discount; boolean hasCar; public Customer() { } public Customer(int age ) { this.age = age; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public double getDiscount() { return discount; } public void setDiscount(double discount) { this.discount = discount; } public boolean getHasCar() { return hasCar; } public void setHasCar(boolean hasCar) { this.hasCar = hasCar; } } {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
