FlashDevelop: getDefinitionByName ReferenceError: Error #1065: Variable ... is not defined.

When I was using getDefinitionByName to create dynamic class.
var myClass:Class = getDefinitionByName('Item1') as Class;

I usually got this error:
[Fault] exception, information=ReferenceError: Error #1065: Variable Item1 is not defined.

Fixed: just including complete library
assets.swf -> Add To Library -> Options -> Included library(include completely)

目前監控 mobile app tracking traffic 常用 proxy monitor 的方式，
不過這種方式常常會出現很謎的狀況，

最準確的方式還是用老方法直接截取封包，
以前用 tcpdump 很苦還要自己解析資料，
幸好現在有 ngrep 好用...XD
