Hello,
First sorry for my bad english
I have a problem when I execute this code

rule "userrole"
when
user1: BnUserValue(name : name, creationDate : creationDate)
and
ActiviteOut : BnNodeValue( BnRole: BnRole )
and
lien: BnEdgeValue(id : id)
then
System.out.println("oui ça marche");
end

BnRole is attribut type ; BnRoleValue (class declared)
when I remote this attribue(BnRole) this code work
all the attribut which I set with type different to classique type (String, Integer, Date, List,... ) implique an error execution I don't know why I import all my class and I'm sure that class haven't error
