JESS: the problem of query working memory

[Weijing Bai]

i hava a problem when use runQueryStar with two params. with only one param
situation it can works well. but with two params it's report:

Jess reported an error in routine runQuery.
  Message: Wrong number of variables for query mid1.
 at jess.Rete.doRunQuery(Rete.java:2889)
 at jess.Rete.runQueryStar(Rete.java:2824)
 at jess.Rete.runQueryStar(Rete.java:2807)
 at test.MidCengSequence(test.java:255)
 at test.TOSequenceADL(test.java:394)
 at test.main(test.java:492)



the program is:


      ValueVector vv = new ValueVector();
      vv.add(jf);
      vv.add(I);
      Value myList = new Value(vv, RU.LIST);
      result = engine.runQueryStar(sRule, new ValueVector().add(myList) );

the clp is :

(defquery mid1
(declare (variables ?x ?i))
     f1<- ();
     f2<-();
)


thanks very much!
