import org.drools.modelcompiler.domain.Person;global java.util.List list;
rule R when
  $p1 : Person(name == "John")
  $p2 : Person(name == "Paul")
then
  list.add($p1.getAge());
  list.add($p2.getAge());
  modify($p1) { setAge($p1.getAge()+1) }
  list.add($p1.getAge());
  list.add($p2.getAge());
  modify($p2) { setAge($p2.getAge()+5) }
