my rule just like this:
==================java code=====================
......
StatefulKnowledgeSession statefulKSession = kbase.newStatefulKnowledgeSession();
Map valueMap = new HashMap();
valueMap.put("year", "2012");
statefulKSession.insert(valueMap);
statefulKSession.fireAllRules();
......
==============================================
=================rule code======================
rule "rule1"
          lock-on-active true
          salience 100
     when
          $map : Map(this["year"] == "2012")
    then
                   System.out.println(drools.getRule().getName());
          //String state = service.getState();
          $map.put("state","2");
          update($m);
end

rule "rule2"
  lock-on-active true
  salience 99
     when
            $map : Map(this["state"] == "2")
    then
          System.out.println(drools.getRule().getName());
end
=============================================

i insert a HashMap as a fact to the working memory
my first rule(rule1) just get "state" from service ,then put into the map then update ,and in the next rule(rule2) judge "state" ,but it never goes into rule2's RHS,why?
