BulkLoader加载swf(loader.content)为空问题解决

public function getContent():*
{
        return null;
}

public var swfContent:Object;
override public function onCompleteHandler(evt : Event) : void {
	// TODO: test for the different behaviour when loading items with 
	// the a specific crossdomain and without one
	try{
		// of no crossdomain has allowed this operation, this might
		// raise a security error
		_content = loader.content;
		swfContent = loader.content;
		super.onCompleteHandler(evt);
	}catch(e : SecurityError){
		// we can still use the Loader object (no dice for accessing it as data
		// though. Oh boy:
		_content = loader;
		super.onCompleteHandler(evt);
		// I am really unsure whether I should throw this event
		// it would be nice, but simply delegating the error handling to user's code 
		// seems cleaner (and it also mimics the Standar API behaviour on this respect)
		//onSecurityErrorHandler(e);
	}
