Question

我正在开发smartGwt项目我开发了简单的slectedItem下拉列表。此下拉列表未显示任何选择的vaules，这是多个选择下拉列表。下面是我的代码

final Window winModal = new Window();
        winModal.setWidth(700);
        winModal.setHeight(400);
        winModal.setAutoSize(true);
        winModal.setTitle("Schedule");
        winModal.setShowMinimizeButton(false);
        winModal.setIsModal(true);
        winModal.setShowModalMask(true);
        winModal.centerInPage();


        DynamicForm form = new DynamicForm();
        form.setHeight100();
        form.setWidth100();
        form.setPadding(5);
        form.setLayoutAlign(VerticalAlignment.BOTTOM);

        SelectItem selectItemMultiplePickList = new SelectItem();  
        selectItemMultiplePickList.setTitle("Select Multiple");  
        selectItemMultiplePickList.setMultiple(true);  
        selectItemMultiplePickList.setMultipleAppearance(MultipleAppearance.PICKLIST);  
        selectItemMultiplePickList.setValueMap("Cat", "Dog", "Giraffe", "Goat", "Marmoset", "Mouse");  

        form.setFields(selectItemMultiplePickList);

        winModal.addItem(form);
        winModal.show();

我的下拉小部件正在显示但未在下拉列表中显示任何值

有点hacky但是使用没有数据源的select的快速方法是设置特殊值：

SlectedItem下拉列表未显示值
