   // injecting this data binder causes automatic binding between
   // the properties of Item and the like-named @DataField members in this class
   // Example: property "" tracks the value in the TextBox "name"
   @Inject @Bound @DataField private TextBox name;
   @Inject @Bound @DataField private TextBox comment;

Not bound because the department name belongs to the nested Department object, not the Item.
   @Inject @DataField private TextBox department;
   @Inject @DataField private Button saveButton;
   private Runnable afterSaveAction;
