我想使用标注来允许重命名。标注包含通过绑定填充的 textInput（嵌入在组件中）。每次打开标注时都会使用不同的文本。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。我附上了一个样本。

我注意到，当标注关闭时将组件附加到视图，然后重新附加到标注，文本输入会正确更新。

欢迎任何帮助。

对于这些情况，您是否尝试过通常的建议——更换皮肤？

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