我在flex中遇到了一些有點奇怪的東西,可能是我做錯了 但我不知道。Flex selectedItem問題
在我注意到的兩種情況下,當s中只有一個項:List或s:DropDownList 出於某種原因使用list.selectedItem時,它顯示爲空。使用requireSelection =「true」 我知道情況並非如此。
有沒有其他人見過類似的東西?或者我是否完全錯誤? 感謝 喬恩
編輯:在代碼波紋管它點擊編輯文件,調用open編輯方法
------------添加的代碼時會發生---- -----------------------
我已刪除一小部分,以使其更易於閱讀

List.selectedItem似乎對我有用,當有一個單數的項目和requireSelection =「true」設置。也許發佈一些代碼?在你檢查了什麼事件之後? – 2011-02-15 19:07:19
