开源开发框架展现出Flex平台的发展势头 http://hi.baidu.com/sinbh/blog/item/75bf161ebbe3ff154134170b.html
Cairngorm（Cairn-gorm）是一个最早最为成熟的FLEX框架,现在已归为ADOBE门下.
PureMVC它其实是一个ActionScript 3框架,不像Cairngorm,它并不是针对FLASH,FLEX或者其它ADOBE AS3.0类。它是一个用于开发基于FLASH的AS 3.0的任何程序.
Model-Glue是一种简单的MVC的FLEX框架,Model-Glue拥有COLDFUSION接口.它相比以上两款更为轻巧.
ServeBox Foundry是一个ActionScript 3/Java框架针对Flex 2应用开发者.
Guasax是一个易用的程序框架,为保证新老FLEX应用的扩展.
ARP (Ariaware RIA Platform)是一个基于ActionScript的框架,它是一个Open Source Flash 项目.
Flest 是一个ActionScript3/Flex框架.

熟悉Flash/Flex 调用数据的接口，熟悉Flash/Flex开发框架和实现机制，有比较强的调试解决问题的能力
熟悉Flash虚拟机的机制
Flex3到Flex4，增加了Spark组件，这是Flex的一次重要升级，基本上组件全部重写了一套，为了保持向下兼容，出现了同一组件两套实现并存的现象，虽然说Spark组件中也可嵌入MX组件，但实际使用常会遇到些小麻烦，例如mx:Tree滚动条异常，透明背景无法监听鼠标事件等等，如果你使用定制的组件，写法稍有不规范，就会出现Spark下显示异常，比如之前定制的TWaver圆角文本输入框就是如此，不得不在Spark下重新实现。
Spark与MX组件的区别
Spark最大的目的或许是方便Adobe兜售它的Flash Catalyst，当然这是个玩笑，Spark组件更加轻量，更易扩展。所有的Flex组件都从UIComponent继承，Spark组件也是如此，只不过它多了一层包装，从SkinnableComponent继承。MX中每个组件对应一个类，在Spark体系中，每个组件对应两个类，一个Component类，一个Skin类，例如按钮组件对应：spark.components.Button和spark.skins.spark.ButtonSkin，这种设计实现了组件行为逻辑与视图呈现的分离，就像将程序员和美工的工作分开一样，这也是MVC思想的产物。
有意思：Java 开始有一个AWT,后台也弄了一个Swing
Flex 3与Flex4的区别详见：

Spark组件外观定制
前面提到Flash Catalyst，这就是Adobe提供的组件外观可视化编辑工具，这个工具主要针对美工、设计师，对于习惯于写代码的程序员们也可以使用Flash Builder 4+来定制组件。
回到实际问题，之前我定制的圆角文本输入框在Spark框架下出现了问题，我决定将其改造，使用定制组件Skin的方式实现圆角文本输入框。
