路径是没有问题的 跟css文件在一个包下面，但是.swf文件无法调用，请各位看看是为什么

错误明显是空指针，看StyleManagerImpl.as:1499的源码，应该是安全域的问题
public function loadStyleDeclarations2(
url:String, update:Boolean = true,
applicationDomain:ApplicationDomain = null,
securityDomain:SecurityDomain……

你好。我的是RIA应用程序，我想用按钮事件触发样式的改变，StyleManager.loadStyleDeclarations("./style/greenstyle.swf");这样用是错的，你能帮我写一个简单的例子吗？谢谢

module.load(applicationDomain, securityDomain);
