将GWT编辑器框架与CellList一起使用

Question

我想将GWT编辑器框架与CellList一起使用.我的数据模型如下所示:

public class CarDto {
   private String name;
   private List<String> features;
   // getter and setter
}

在这里使用GWTP是我的演示者的一部分:

public class Presenter {

  public interface MyView extends View, Editor<CarDto> {
  }

  private final SimpleBeanEditorDriver<CarDto, ?> editorDriver;

  public Presenter(...) {
      editorDriver = getView().createEditorDriver();
  } 
  ...

  @Override
  public void saveButtonClicked() { 
    CarDto carDto = editorDriver.flush();
    int size = carDto.getFeatures().size();  // result is 0
  }

}

我的View类:

public class CarView implements Presenter.MyView {

   public interface EditorDriver extends SimpleBeanEditorDriver<CarDto, CarView> {   
   }


   @Path(value="name")
   @UiField
   TextBox nameInput;   // editor works fine with this

   @Path(value="features")   // this editor is not working !!!
   ListEditor<String, LeafValueEditor<String>> featuresEditor;

   @UiField
   CellList<String> cellList;  
   ListDataProvider<String> dataProvider;

   public CarView() {
     dataProvider = new ListDataProvider<String>();
     dataProvider.addDataDisplay(cellList);
     featuresEditor = HasDataEditor.of(cellList);
   }


   // create the editor driver
   @Override
   public SimpleBeanEditorDriver<CarDto, ?> createEditorDriver() {
     EditorDriver driver = GWT.create(EditorDriver.class);
     driver.initialize(this);
     return driver;
   }


  @UiHandler("save")
  protected void saveClicked(ClickEvent e) {
    List<String> dtos = dataProvider.getList();
    dtos.add("test");
    getUiHandlers().saveButtonClicked();
  }
}

当我点击保存按钮并editorDriver.flush()在我的演示者中进行操作时,我只name 从视图中获取属性CarDto.功能列表始终为空.

我必须featuresEditor像这样改变手动的值:

featuresEditor.getList().add(...);

我刷新后在列表中进行更改.这意味着我必须设置两个列表来维护数据:

featuresEditor.getList().add(...);
dataProvider.getList().add(...);

这似乎不正确.

当dataProvider列表更改时,如何才能实现ListEditor的正确更新？如何正确设置编辑器以使用List<String>由CellList？处理的编辑器？
