Thanks a lot for the quick and right answer! :-) Unfortunately this seams not work properly when I try to use the multislot value like a list. Trying to read an element of the list, Jess gives me this error:
Message: '<Java-Object:jess.aj>' is JAVA_OBJECT, not a list. isn't a Class-defined array still a multislot? My class is called Relation and its multislot is called multiplicityFrom, the following line (taken from a rule) is that one that generate the error: (Relation (name ?n) (multiplicityFrom ?a $?list)) many thanks again!
