Flex自定义组件不接受脚本：默认属性“文本”，“字符串”类型的多个初始值设定项值

问题描述

我使用的是Flex 4和Flash Builder 4.我只是想学习创建组件，我创建了一个mxml组件，并将其包含在我的应用程序中：

 <？xml version =1.0encoding =utf-8？> 
  xmlns：s =library：//ns.adobe.com/flex/spark 
 xmlns：mx =library：//ns.adobe.com/flex/mx> 
< fx：Script> 
< / fx：Script> 
< / s：TextInput> 
  

如果我将fx：Script标签取出，但只要有这些标签不管是否有实际的代码在那里）我得到的错误：Flex自定义组件不接受脚本：默认属性，'文本'，'字符串'类型的多个初始值。

为什么会这样呢？是不是在组件允许脚本？

解决方案

这是一个已知的bug 。里程碑是下一个Flex SDK英雄版本。如果您明确设置了 text 属性，您仍然可以使用mxml。

 <？xml version = 1.0encoding =utf-8？> 
  xmlns：s =library：//ns.adobe.com/flex/spark 
 xmlns：mx =library：//ns.adobe.com/flex/mx
 text => 
< fx：声明> 
 < / fx：声明> 
< / s：TextInput> 
  

谢谢。

I'm using Flex 4 and Flash Builder 4. I just want to learn to create components and I created an mxml component as follows and included it in my application:

<?xml version="1.0" encoding="utf-8"?>
<s:TextInput xmlns:fx="http://ns.adobe.com/mxml/2009" 
             xmlns:s="library://ns.adobe.com/flex/spark" 
             xmlns:mx="library://ns.adobe.com/flex/mx">
    <fx:Script>
    </fx:Script>
</s:TextInput>

If I take out the fx:Script tags it works, but as soon as I have those tags (regardless of whether any actual code is in there) I get the error: "Flex custom component doesn't accept script: Multiple initializer values for default property, 'text', of type 'String'."

Why would that be? Is script not allowed in components?

解决方案

this is a known bug SDK-25184. Milestone is the next Flex SDK Hero Release. You still can use mxml if you explicitly set the text property.

<?xml version="1.0" encoding="utf-8"?>
<s:TextInput xmlns:fx="http://ns.adobe.com/mxml/2009" 
             xmlns:s="library://ns.adobe.com/flex/spark" 
             xmlns:mx="library://ns.adobe.com/flex/mx"
             text="">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
</s:TextInput>

Thanks.
