Hello to jess community,
I have a problem with the patterns of a rule
In my clp file I have defined:
(deftemplate Door(declare (from-class Door )))
(deftemplate User(declare (from-class User )))
(defrule MainDoor-rule
(Door {mainDoorState == "closed"})
(User {userLocation == "NearDoorRegion" })
=>
(printout t "@@@ YES @@@:" crlf))
Door,User are the Bean classes which contain the required methods:
getmainDoorState, getuserLocation
I add an instance of each class into WM but the rule never fires even
though it calls correctly the above methods.
But if I try to reject one LHS condition , the rule fires normally...
Why this happens?
Should I add something to the syntax of the rule
in order to check both conditions??
thanks in advance,
