As discussed in presence the previous solution in ReactiveList :

{code:java}
    @Override
    public boolean add(T t) {
        boolean result = list.add(t);
        ReactiveObjectUtil.notifyModification(t, getLeftTuples(), ModificationType.ADD);
        if (t instanceof ReactiveObject) {
            for (Tuple lts : getLeftTuples()) {
                ((ReactiveObject) t).addLeftTuple(lts);
            }
        }
        return result;
    }
{code}

is not really ideal as this case fails by creating twice the match:

{code:java}
    @Test
    public void testMatteo2() {
        String drl =
                "import org.drools.compiler.xpath.*;\n" +
                "global java.util.List list\n" +
                "\n" +
                "rule R when\n" +
                "  Man( $usage: /wife/children{age > 10}/toys/usage{level > 10} )\n" +
                "then\n" +
                "  list.add( $usage );\n" +
                "end\n";

        KieBase kbase = new KieHelper().addContent( drl, ResourceType.DRL ).build();
        KieSession ksession = kbase.newKieSession();

        List<String> list = new ArrayList<String>();
        ksession.setGlobal( "list", list );

        Woman alice = new Woman( "Alice", 38 );
        Man bob = new Man( "Bob", 40 );
        bob.setWife( alice );

        ksession.insert( bob );
        ksession.fireAllRules();
        
        list.clear();
        Child eleonor = new Child( "Eleonor", 10 );
        alice.addChild( eleonor );
        Toy toy = new Toy( "eleonor toy 1" );
        eleonor.addToy( toy );
        Usage usage = new Usage();
        toy.setUsage(usage);
        usage.setLevel(99);
        eleonor.setAge(11);
        ksession.fireAllRules();
        System.out.println(list);
        

        usage.setLevel(99);
        ksession.fireAllRules();
        System.out.println(list);
    }
{code}
