GWT列表編輯器綁定

Question

public interface Person {
    String getName();
    void setName(String name);
    List<PersonFriend> getFriends();
}

public interface PersonFriend {
    String getName();
}

我正在嘗試為Person實現一個只查看編輯器：

public class PersonViewEditor extends Composite implements Editor<Person> {
    private static PersonViewEditorUiBinder uiBinder = GWT.create(PersonViewEditorUiBinder.class);
    interface PersonViewEditorUiBinder extends UiBinder<Widget, PersonViewEditor> {}

    @UiField Label nameEditor;
    @UiField PersonFriendsViewEditor friendsEditor;

    @UiField FancyAnchor editAnchor;

    public PersonViewEditor(ClientFactory clientFactory) {
        initWidget(uiBinder.createAndBindUi(this));
        editAnchor.setPlace(
                clientFactory.getPlaceHistoryMapper(), 
                clientFactory.getPlaceController(), 
                new EditPersonPlace());
    }
}

public class PersonFriendsViewEditor extends Composite {
    private static PersonFriendsViewEditorUiBinder uiBinder = GWT.create(PersonFriendsViewEditorUiBinder.class);
    interface PersonFriendsViewEditorUiBinder extends UiBinder<Widget, PersonFriendsViewEditor> {}

    interface Driver extends SimpleBeanEditorDriver<List<PersonFriend>, ListEditor<PersonFriend, PersonFriendViewEditor>> {}

    private class PersonFriendViewEditorSource extends EditorSource<PersonFriendViewEditor> {
        @Override
        public PersonFriendViewEditor create(int index) {
            PersonFriendViewEditor friend = new PersonFriendViewEditor();
            containerPanel.insert(friend, index);       
            return friend;
        }       
    }

    @UiField HorizontalPanel containerPanel;

    public PersonFriendsViewEditor() {
        initWidget(uiBinder.createAndBindUi(this));     
        Driver driver = GWT.create(Driver.class);
        ListEditor<PersonFriend, PersonFriendViewEditor> editor = ListEditor.of(new PersonFriendViewEditorSource());
        driver.initialize(editor);  
    }
}

當我綁定Person對象PersonViewEditor ， friendsEditor永遠不會綁定到人的朋友列表。 看起來PersonFriendsViewEditor應該實現一些魔術接口以允許GWT與它交互，但我找不到任何相關的文檔。 在GWT中有dynatablerf示例，但是它們明確地綁定了它們的列表編輯器，我很好奇將它綁定為“外部”對象的一部分，所以我只是將Person綁定到PersonViewEditor並且它擁有所有數據/設置所有小部件。

有什么想法嗎？

PersonFriendsViewEditor應該實現IsEditor<ListEditor<PersonFriend, PersonFriendViewEditor>> - 解決了這個問題。
