thanks for your attention Brandon ! I didn't understand your first way completely. I don't use App engine. our application use spring and jpa and I use eclipse and currently we run application on jetty. in our previous application, we used jsf and we could implement such scenarios for entities with owned collection and after copying collections from ui into entity, hibernate handle persisting entity and it's owned collection and we didn't do anything. in that application when we annotate a property with cascade="all-delete- orphan" and ask hibernate to save(entity), it saves it's owned collections too.
I want to know how to implement such scenarios, when we use gwt 2.4 with editor framework. and is there any sample or tutorial for doing this on web ?
