Hi, In "stateless" Session: If List of A1,B1,C1 are executed - execute(List) and at the same time in a paralell thread A2,B2,C2 are executed - execute(List) In "Theory" (Conceptually), I want to confirm if A1 will interfere with the rule using A2? Just want to ensure what is appropriate or expecteed behavior. ...assuming both threads hit the same session for that "delta t" period of time. thanks, arjun _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
