Java SmartGwt ListGrid.SetAlwaysShowEditor（true）问题

我们有一个基本的ListGrid，其中一个字段是可编辑的，应该始终显示该字段的编辑器，下面是创建代码

ListGrid listPanel = new ListGrid();
listPanel.setDataFetchMode(FetchMode.PAGED);
listPanel.setDataSource(datasource);
listPanel.setAutoFetchData(true);
listPanel.setAlwaysShowEditors(true);
listPanel.setCanEdit(true);
listPanel.setAutoSaveEdits(false);
listPanel.setSaveByCell(false);
listPanel.setEditOnFocus(true);
listPanel.setEditEvent(ListGridEditEvent.CLICK);

此处创建可编辑字段

ListGridField manualScoreColumn = new ListGridField("score", "Score");
manualScoreColumn.setType(ListGridFieldType.INTEGER);
manualScoreColumn.setCanEdit(true);
manualScoreColumn.setValidateOnChange(true);
manualScoreColumn.setValidators(new IntegerRangeValidator());

问题是当ListGrid中的数据使用

listPanel.setCriteria(criteria);

我们得到这样的豁免

12:42:31.204:RDQ2:WARN:Log:TypeError: _5 is null
ListGrid._clearingInactiveEditorHTML() @ adminApp/sc/modules/ISC_Grids.js:1530

我发现了类似的问题，但没有提出解决方案

有什么解决办法吗？谢谢。

请确保已将ListGridField设置为ListGrid

 listPanel.setFields(manualScoreColumn);

将您选择的编辑器设置为ListGridField的另一种方法是使用setEditorType方法

    ListGrid listPanel = new ListGrid();
    listPanel.setCanEdit(true);
    listPanel.setAutoSaveEdits(false);

    //You can use any formitem instead of date item,Say TextItem,SelectItem etc
    DateItem dateItem = new DateItem();
    ListGridField dateListGridField= new ListGridField("date", "Date");
    dateListGridField.setEditorType(dateItem);
    listPanel.setFields(dateListGridField);
