RequestFactory GWT中EntityProxy中的OneToMany关系

Question

I have a problem with EntityProxies in RequestFactory.

@ProxyFor(value=Day.class, locator = DayLocator.class)
public interface DayProxy extends EntityProxy{

      List<OrganizerEntryProxy> getEntries();
      void setEntries(List<OrganizerEntryProxy> entries);
      etc...
}

Entity:

public class Day implements Serializable {

    private List<OrganizerEntry> entries;
        etc...

        public List<OrganizerEntry> getEntries(){
        return Collections.unmodifiableList(entries);
    }

    public void  setEntries(List<OrganizerEntry> entries){
        this.entries = entries;
    }
        etc....
}

OrganizerEntryProxy is EntityProxy not ValueProxy .

Now, when in service, I send a Day instance to the client with OrganizerEntry List containing OrganizerEntry entities. When it is received at the client DayProxy.getEntries() returns null. Retrieving OrganizerEntity alone works allright.

What am I doing wrong?

Hah, mystery unveiled. It was rather basic problem. I had to add .with("entries").fire(. . to the call. It seems stupid but all the information I had was from http://www.gwtproject.org/doc/latest/DevGuideRequestFactory.html and some HelloWorld internet examples. Is there more detailed documentation to RequestFactory?
