DatePickerCell打破錶格選擇

Question

當我單擊DatePickerCell的單元格時，表格選擇不再起作用。下面

表剛剛2列：日期，文本

與GWT測試的2.4和2.5 測試了Chrome瀏覽器，IE9

有什麼不對的代碼貼？

是否有與SelectionModel和DateCellPicker的DataGrid的工作示例的鏈接，該選擇工作正常？

一個工作示例將回答我的問題。

UPDATE：

我貼一個完整的可運行的例子。

Answer 1

從什麼AbstractCellTable的源代碼的模樣，你真的必須要麼使用KeyboardSelectionPolicy.BOUND_TO_SELECTION或提供處理選擇至少一種細胞類型。
