Re: JESS: get object from a list

I am working on protege 3.4.4 with JessTab and the query is in Jess!
You are right, i am getting a real java.util.List and i could print out the
list (i haven't tried it yet, i suppose it would work) but how can i sort
out some of the elements of the list. i think it is better if i send you the
code so you can see what i really want to do. i tried to write it as
detailed as possible with comments and everything.
thank you very much fo your time.
