Hi all,
I'm just starting out with Jess here and I'm unsure how to access Fact members
I have a simple JavaBean containing an ArrayList and defined that with
"(deftemplate Watchlist (declare (from-class Watchlist)))"
After inserting the Fact I'd like to use a rule to check if the ArrayList
contains a value:
(defrule person-on-evildoer-watchlist
?evildoers <- (Watchlist {category == "evildoers"})
(call ?evildoers.watchedNames contains "Dr. Evil")
=>
(printout t "Suspicious!")
)
Even though the "watchedNames" ArrayList does contain the specified value, the
rule does not fire. It does fire when I comment out the "call" function, so I
suspect I'm doing something wrong when checking the contents of the List.
Could you point me in the right direction here?
Thanks,
Jörg Henschel
