RE: JESS: Any Ideas

[Orchard, Bob]

I've made a few changes to the program provided with JIA for fuzzy control
to allow one to change the setpoint as well as the outside temperature.
In this case there will be 2 text boxes. The top one is the outside temp and
the bottom the setpoint temp. It involved small changes to 3 files that
are enclosed with this message. The changes include adding a getSetPoint
method
to the Simulator class and string the setpoint in that class. In the
clp file it was necessary to use this method to get the current
setpoint in a few places ... using the syntax Ernest described in his
response to
this message.

Hi guys,
 
Anyone knows what is an async error  as follows?
 
Async Error: Jess reported an error in routine Funcall.execute
            while executing (SetPoint (setpoint ?value))
            while executing deffunction too-cold
            while executing (too-cold ?t)
            while executing rule LHS (TEQ)
            while executing rule LHS (TECT).
 
This is regarding the HVAC simulation.
What I did was I changed the ?*set-point* parameter to a bean. 
That is, I want to dynamically change the set point of the simulation from
the java infrastructure (I thought it would be more realistic that way). 
I made SetPoint as a defclass and subsequently definstance instead. 
 
The error seems to come from 
 
(deffunction too-cold (?t)
            (SetPoint (setpoint ?value))  
            (return (< ?t (- ?value 2))))
 
I think my understanding of some jess issues must be faulty. 
Would appreciate any advice and pointers.
 
 
Regards
David
