在标注中多次使用textInput时Flex4.6移动绑定不起作用

Question

我想使用标注以允许重命名。 该标注包含通过绑定填充的textInput（嵌入在组件中）。 标注每次都以不同的文本打开。不幸的是，每次只显示第一个文本，无论我可以写入绑定数据。 我附上了一个示例。

我注意到，当组件附加到查看标注关闭时，然后重新附加到标注，文本输入更新正确。

任何帮助将受到欢迎。

您是否尝试过这些情况下的常见建议 - to change the skin？

<s:TextInput skinClass="spark.skins.mobile.TextInputSkin" id="Nom" 
text="{_nom}" width="201" maxChars="23" restrict="a-z A-Z0-9" />
