Question

大家好我在使用mozilla浏览器的Windows上使用智能gwt 2.2。

我正在使用包含两个字段的列表网格。我将第二个字段的编辑器类型设置为SelectItem。在该选择项中，我正在渲染网格。对于选择项目，我设置了值字段和显示字段。

但是从选择项目中选择任何项目后，它是显示值字段。我也附上了它的代码。

网格代码

public void initializeGrid() {
  ListGrid grid = new ListGrid();
  setGridProperty(grid);
  grid.setFields(getGridFields());
  grid.setData(getGridData());
  getSmartContainer().addChild(grid);
 }

 private static ListGridRecord[] getGridData() {
  ListGridRecord record = new ListGridRecord();
  record.setAttribute("id", "");
  record.setAttribute("name", "");

                ListGridRecord record1 = new ListGridRecord();
  record1.setAttribute("id", "");
  record1.setAttribute("name", "");

  return new ListGridRecord[] { record, record1 };
 }

 private static void setGridProperty(ListGrid grid) {
  grid.setWidth("90%");
  grid.setHeight(125);
  grid.setCanEdit(true);
  grid.setEditEvent(ListGridEditEvent.CLICK);
  grid.setEditByCell(true);
  grid.setAlternateRecordStyles(true);
  grid.setShowAllRecords(true);
 }

 private static ListGridField[] getGridFields() {
  ListGridField field = new ListGridField("id");
  FormItem item = new TextItem();
  field.setEditorType(item);

  ListGridField field1 = new ListGridField("name");
  SelectItem item1 = new SelectItem("name");
  setPropertyForSelectitem(item1);
  DataSource dataSource = new DataSource();
  dataSource.setClientOnly(true);
  item1.setOptionDataSource(dataSource);
  setDataForSelectItem(dataSource);
  field1.setEditorType(item1);

                return new ListGridField[] { field, field1 };
 }

选择项目的代码

public static void setDataForSelectItem(DataSource dataSource) {
  for (int i = 0; i < 2; i++) {
   ListGridRecord record = new ListGridRecord();
   record.setAttribute("id", "1");
   record.setAttribute("name", "name" + i);
   record.setAttribute("address", "address" + i);
   dataSource.addData(record);
  }
 }

 private static void setPropertyForSelectitem(SelectItem item) {
  item.setPickListFields(getFieldsForSelectItem());
  item.setWidth(150);
  item.setValueField("id");
  item.setDisplayField("name");
  item.setPickListWidth(250);
 }

 private static ListGridField[] getFieldsForSelectItem() {
  ListGridField idField = new ListGridField("id");
  ListGridField nameField = new ListGridField("name");
  ListGridField addField = new ListGridField("address");
  return new ListGridField[] {idField,nameField,addField };
 }

绘制此网格后，它是选择项的渲染值字段，但我想渲染名称（因为它是选择项的显示字段）。

我在动态表单中使用的相同项目，但它在那个地方运行良好，但对于网格，它运行不正常。请帮忙。谢谢
