Hello,
Thanks for your quick answer. I know it's hard to debug a program when
you're not in front of it.
The details suggest to me that there are two Controller facts. Are you
sure there's only one?
I have just rewritten the rule as following :
(defrule PROCESS::process-entity
?fact1 <- (MAIN::Station (disabled FALSE)
(processing FALSE)
(OBJECT ?station&:
(canBeginProcessing
?station)))
?fact2 <- (MAIN::Controller(time ?time))
=>
(printout t "process-entity fired" crlf)
(printout t "Station fact is " ?fact1 crlf)
(printout t "Controller fact is " ?fact2 crlf)
..)
And according the console windows it seems there is only one Controller
fact, it's displayed :
process-entity fired
Station fact is <Fact-18>
Simulation fact is <Fact-42>
process-entity fired
Station fact is <Fact-18>
Simulation fact is <Fact-42>
But don't bother to much with my problem if you don't have time. After all,
as I said in the previous message, it is functional if I use pattern
binding. But I still wondering why ...
Cheers !
Nicolas
