[rules-users] object problem

[fakhfakh ismail]

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
thank you for your help
Best regards
Ismail
