Question

我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。以下错误是否表示验证器有错误或label.text的默认值是错误的？

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“Text”（带有大写字母T）。 TextInput的{{1}}属性为小写“t”。

听起来您已配置text以验证错误的属性名称。也就是说，你这样做：

Validator

应该如此：

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

代码中的未知错误
