如何在Vaadin表中默认选中的每一行中选中复选框？

Question

我是Vaddin的新手。 如何在Vaadin表中默认选中的每一行中选中复选框？ 我已经通过一些Vaadin示例，通过编写“field.setValue（true）”来指定将在每行中选中复选框。但解决方案对我不起作用。请帮我找出下面代码我出错的地方。在这里，我使用DefaultFieldFactory为每一行生成字段。

public class ReviewTimesheetTable extends ViewComponent {

private Map<ReviewTimesheetTableDto, HashMap<String, AbstractField<?>>> tableItem = new HashMap<ReviewTimesheetTableDto, HashMap<String, AbstractField<?>>>();
BeanItemContainer<ReviewTimesheetTableDto> data = new BeanItemContainer<ReviewTimesheetTableDto>(
        ReviewTimesheetTableDto.class);
private Table table;

public void init() {
    // Create a data source and bind it to a table
    table = new Table("", data);
    table.addStyleName("generateColumnTable");
    table.setWidth("100%");
    table.setPageLength(table.getItemIds().size());
    table.setVisibleColumns(new Object[] { "chkBox", "taskDate", "employeeId", "taskId", "crJiraId",
            "taskDesc","hour","minute"/*, "Delete" */});

    table.setColumnHeader("chkBox", "Select");
    table.setColumnHeader("taskDate", "Task Date");
    table.setColumnHeader("employeeId", "Employee ID");
    table.setColumnHeader("taskId", "Task ID");
    table.setColumnHeader("crJiraId", "Subtask ID");
    table.setColumnHeader("taskDesc", "Task Description");
    table.setColumnHeader("hour", "Hour");
    table.setColumnHeader("minute", "Minute");

    table.setEditable(true);

    table.setTableFieldFactory(new ImmediateFieldFactory());
}
public class ImmediateFieldFactory extends DefaultFieldFactory {

    @Override
    public Field<?> createField(Container container, Object itemId,
            Object propertyId, Component uiContext) {
        final ReviewTimesheetTableDto timesheetDetail = (ReviewTimesheetTableDto) itemId;

        Map<String, AbstractField<?>> tableRow = null;

        if(tableItem.get(timesheetDetail) == null)
        {
            tableItem.put(timesheetDetail,
                    new HashMap<String, AbstractField<?>>());

        }
        tableRow = tableItem.get(timesheetDetail);

        if ("taskId".equals(propertyId)) {
