Re: JESS: A question about Rete object.

[Calicrates Policroniades Borraz]

I think I have found the source of my previous error, I will correct
it. Thank you.

Now I have the next doubt.

There is some difference between:

(defrule one-rule
   (element (name "ball"))
....

and

(defrule one-rule
   (element (name "Ball"))
...

I mean, Is it the case sensitive supported in thi case?

Thank you....
