Hi Brian,
If you can send me a self-contained example that reproduces the
problem you're seeing, we'd be happy to take a look at it, and if it
represents a bug, happy to fix it for the next release.

Hi,
I am wondering if anyone is experience problems with salience using
Jess 7. Since moving to Jess 7, I have noticed recently a strange
occurrence where a rule with a higher salience is activated but is
not fired. Then a rule with a lower salience is fired. Here is a
notional example:
There are a several rules with a salience offset by 25. According
to my understanding of salience, modc::x should fire on all
matching facts before modc::y.
(defrule modc::x
(declare (salience 5400))
…)
… other rules with saliences < 5400 and >= 5150 …
(defrule modc::y
(declare (salience 5125))
…)
Then when running the rules, the output includes:
FIRE 128 modc::y f-178,,
==> f-288 (MAIN::output …)
<== Activation: modc::x : f-191, f-82,,
To fix the problem I have rewritten the rules using a separate
module for each rule instead of salience. But I am wondering what
the cause of the problem is and if salience should no longer be
trusted in Jess 7.
Thanks in advance,
Brian
