flex加載xml文件報安全錯誤

初學Flex就碰到安全沙箱問題:
*** 安全沙箱衝突 ***
到 data/maps/demo1.xml 的連接已停止 - 不允許從 file:///D:/FlexWorkspace/MapDemo/bin-debug/MapDemo.swf 進行連接
[color=red]
SecurityError: Error #2148: SWF 文件 file:///D:/FlexWorkspace/MapDemo/bin-debug/MapDemo.swf 不能訪問本地資源 data/maps/demo1.xml。只有僅限於文件系統的 SWF 文件和可信的本地 SWF 文件可以訪問本地資源。

flex項目上點右鍵-->properties-->ActionscriptCompiler-->Additional compiler arguments
加上 “ -use-network=false ” 就OK了

swf就無法訪問網絡資源了，比如socket通訊之類的.

暫時就這樣用下,以後有更好的方法再更新
