Missing alpha node removal when the only rule using it is removed ----------------------------------------------------------------- Key: DROOLS-891 URL: https://issues.jboss.org/browse/DROOLS-891 Project: Drools Issue Type: Bug Reporter: Mario Fusco Assignee: Mario Fusco Fix For: 6.3.0.CR2 When an alpha node has more than one sink and it is used by only one rule doesn't get removed when the rule itself is removed. The following test case demonstrates the problem. {code} @Test public void testRemoveHasSameConElement() { String packageName = "test"; String rule1 = "package " + packageName + ";" + "import java.util.Map; \n" + "rule 'rule1' \n" + "when \n" + " Map(this['type'] == 'Goods' && this['brand'] == 'a') \n" + " Map(this['type'] == 'Goods' && this['category'] == 'b') \n" + "then \n" + "System.out.println('test rule 1'); \n"+ "end"; KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newByteArrayResource( rule1.getBytes() ), ResourceType.DRL ); if ( kbuilder.hasErrors() ) { fail( kbuilder.getErrors().toString() ); } KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); kbase.removeKnowledgePackage(packageName); StatelessKnowledgeSession session = kbase.newStatelessKnowledgeSession(); session.execute(new HashMap()); } {code}
