Hi, Well it depends whether you really like to use expression fro assignment or not. If not then its easy because jbpm use String datatype to store actorIds. Hence you can use your own IdentityComponent ini AssignmentHandler's assign method. You don't have to tell jbpm anything about your IC(IdentityComponent). But if you would like to use expressionhandler then its not that easy. It has small dependency on IC provided by Jbpm. Cheers!!!!!!
