Hi Mitch,
Perhaps this is a candidate for the new "accumulate" function!?
(defrule count-assignment-children
?c <- (accumulate (bind ?count 0)
(bind ?count (+ ?count 1))
?count
(assignment (key ?key&:(eq ?key "child"))))
=>
(if (= ?count 1) then
(printout t "there is only one assignment with key=child" crlf))
;; Do something cool with ?c
)
Cheers,
Jason
