OK, so you don't need to know about ServiceLayerDecorator. What you askfor was already possible in GWT 2.1.0, but your "business methods" had to be static (but not necessarily on your entity classes!). With GWT 2.1.1 you'll give a ServiceLocator so RequestFactory will be able to create an instance of your object implementing your business logic (as either static or instance methods). And similarly, you'll provide a Locator for your entities so RequestFactory can "find" them without resorting to a findXxx static method on the entity class. I've finally spent a couple hours writing a log post about RequestFactory: http://tbroyer.posterous.com/gwt-211-requestfactory @David: could you please update the online JavaDoc? I currently have broken links, and some others might provide misleading information (e.g. InstanceRequest and RequestContext#create had EntityProxy bounds in 2.1.0 when they now have BaseProxy bounds) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
