Flex用filereference上传文件firefox下报2038错误

Flex Code :

var urlVars:URLVariables = new URLVariables();
urlVars.jsessionid = sessionID;

var uploadUrl:String = “http://localhost:8080/mywar;jsessionid=”+sessionID;
uploadUrl += “?”+getClientCookies(); //put all client cookies on the query string
var urlRequest:URLRequest = new URLRequest(uploadUrl);
urlRequest.method = URLRequestMethod.POST;
urlRequest.data = urlVars;

//will go first time and get the cookies set see flex docs
var testUpload:Boolean = true;
fileRef.upload(urlRequest,”Filedata”,testUpload);
