I have several flex modules in my application. One of my module implements login ability. Through that module I load User entity from remoting service, but User entity has oneToMany association - UserAccSubscription, that association is represented as ListCollectionView so the class UserAccSubscription is not mentioned here. The problem is that when the module try to externalize that association, application error appear. I think that the reason is that UserAccSubscription class is not linked into my module although the class is compiled into RSL in my web application. I dont want to static link that class into application. Please help!
