Here is the rule which compiles fine :
(defrule MessageCountUnreadUpdate
(MessageItem (reference ?r) (context ?c) (author ?a) (status
"unread"))
?f1 <- (MessageCount (context ?c)
(author ?a)
(unread ?u)
(messages $?m)
)
(test (not (or (member$ ?r $?m))))
(ContextItem (context ?c))
(not (ContextItem (context ?c2&:(> ?c2 ?c))))
=>
(modify ?f1 (unread (+ 1 ?u))
(messages (insert$ $?m (+ 1 (length$ $?m)) (create$ ?r)))
)
)
Here is the execution trace :
