RE: [rules-users] Problem with Student - module example

I assume you also insert s1 and m1 to working memory? What if you re-write the rule as two patterns (there is an implicit AND between patterns) Rule: $student : Student() Module( student == $student && score > 40 ) ) With kind regards, Mike -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Dave, Rajeev Sent: 20 August 2007 13:02 To: Rules Users List Subject: [rules-users] Problem with Student - module example Given: Student.java public class Student { private String name; private ArrayList modules = new ArrayList(); ... } Module.java public class Module { private String name; private Student student; private int score; ... } Rule: exists( $student : Student() && Module( student == $student && score > 40 ) ) Problem statement: I assert 2 Students and 2 modules in the session Student s = new Student(), s1 = new Student(); Module m = new Module(), m1 = new Module(); m.setName("English"); m.setStudent(s); m.setScore(10); s.setName("abc"); s.addModule(m); m1.setName("English1"); m1.setStudent(s1); m1.setScore(50); s1.setName("xyz"); s1.addModule(m1); workingMemory.insert(m); workingMemory.insert(s); Result: I get 2 activations. I am expecting only 1 activation as only xyz student has score > 40 Am I missing something or is this a bug?
