[jboss-jira] [JBoss JIRA] Closed: (JBRULES-2274) Rule does not fire as expected using deep object model and nested 'or' clause

Rule does not fire as expected using deep object model and nested 'or' clause ----------------------------------------------------------------------------- Key: JBRULES-2274 URL: https://issues.jboss.org/browse/JBRULES-2274 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.0.1.FINAL Environment: Windows XP with JBoss 4.2.2GA using the 5.0.1 jars for core, compiler and api. Reporter: Brian DeCamp Assignee: Edson Tirelli Fix For: 5.2.0.CR1 When combining deep facts and nested 'or' statements, rules do not fire. I've reduced the problem as much as possible with the following example: Note: I've used 'eval(true)' in this example, but it also happens with any expression that evaluates to true in the or clause. ------- begin test.drl -------- rule "find one and two with 'or' clause - WORKS" when com.xyz.SimpleFact(name == "one"); (eval(true) or eval(true)); com.xyz.SimpleFact(name == "two"); then System.out.println("found one and two with 'or' clause"); end rule "Deep one and two without 'or' - WORKS" when d1: com.xyz.DeepFact(); com.xyz.SimpleFact(name=="one") from d1.simple; d2: com.xyz.DeepFact(); com.xyz.SimpleFact(name=="two") from d2.simple; then System.out.println("Found deep facts with simple facts one and two without 'or' clause"); end rule "Deep one and two with nested 'or' - FAILURE!!!" when d1: com.xyz.DeepFact(); com.xyz.SimpleFact(name=="one") from d1.simple; (eval(true) or eval(true)); d2: com.xyz.DeepFact(); com.xyz.SimpleFact(name=="two") from d2.simple; then System.out.println("THIS DOES NOT FIRE"); end -------end test.drl -------- ------- begin DeepFact.java -------- package com.xyz; public class DeepFact { private SimpleFact simple; public SimpleFact getSimple() { return simple; } public void setSimple(SimpleFact simple) { this.simple = simple; } } ------- end DeepFact.java -------- ------- begin SimpleFact.java -------- package com.xyz; public class SimpleFact { private String name; public SimpleFact() {} public SimpleFact(String name) { this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } } ------- end SimpleFact.java -------- ------- begin test code------- public void testRules() { KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); org.drools.io.Resource ruleResource; try { ruleResource = ResourceFactory.newInputStreamResource(new FileInputStream("test.drl")); } catch (FileNotFoundException e) { throw new RuntimeException(e); } kbuilder.add(ruleResource, ResourceType.DRL); if ( kbuilder.hasErrors() ) { System.err.println( kbuilder.getErrors().toString() ); } Collection<KnowledgePackage> compiledPackages = kbuilder.getKnowledgePackages(); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(compiledPackages); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); // Insert facts ksession.insert(new SimpleFact("one")); ksession.insert(new SimpleFact("two")); DeepFact d1 = new DeepFact(); d1.setSimple(new SimpleFact("one")); ksession.insert(d1); DeepFact d2 = new DeepFact(); d2.setSimple(new SimpleFact("two")); ksession.insert(d2); ksession.fireAllRules(); ksession.dispose(); } ------- end test code --------
