我已经用验证器创建了一个表单。每次代码运行到 label.text 或与 label.text 相关的函数时，都会弹出以下错误。以下错误是否意味着验证器有错误或 label.text 的默认值错误？

ReferenceError: Error #1069: Property Text not found on spark.components.TextInput and there is no default value.

请注意，错误表示未找到属性“文本”（大写 T）。TextInput有一个text带有小写“t”的属性。

听起来您已将 配置Validator为验证不正确的属性名称。也就是说，你正在这样做：

<mx:Validator source="{myTextInput} property="Text" />

什么时候应该是这样的：

<mx:Validator source="{myTextInput} property="text" />
