[Jboss Rules] - using constraints in LHS

[viben2512]

I am discovering jboss rules (drools 4.0.7). I try to reproduce the example 'State' of drools.
The drools version works fine.
But in my version, the rules are not fired and I do not understand why .... It is so basic I do not see where my mistake is. Please help

the rule

package examples.statemachine

import com.corp.drools.examples.statemachine.State;

rule Bootstrap
 when
 a : State(name == "A" )
 then
 System.out.println(a.getName() + " finished" );
 a.setState( State.STATE_FINISHED );
end

the class State

public static final Integer STATE_NOTRUN = new Integer(0);
public static final Integer STATE_FINISHED = new Integer(1);

public State(final String name) {
 this.name = name;
 this.state = State.STATE_NOTRUN;
}

private String name;
private Integer state;
// ... getter, setter

the test case :

public void test2() throws Exception {
 final PackageBuilder builder = new PackageBuilder();
 builder.addPackageFromDrl(new InputStreamReader(
this.getClass().getClassLoader().getResourceAsStream("examples/statemachine/rules.drl")));

 RuleBase ruleBase = RuleBaseFactory.newRuleBase();
 ruleBase.addPackage(builder.getPackage());
 StatefulSession session = ruleBase.newStatefulSession();

 WorkingMemoryConsoleLogger logger = new WorkingMemoryConsoleLogger(session);

 State[] objects = new State[] { new State("A") };
 session.insert(objects[0]);
 session.fireAllRules();

 session.dispose();
 Assert.assertEquals(State.STATE_FINISHED, objects[0].getState());
}

the test case output :

OBJECT ASSERTED value:A-0 factId: 1
