I met with a problem when learning the flex in a week.
In Day4 session, "Introducing the MVC pattern", after I created a dataService as suggested, I tried to test operation, there's an error: "invocationtargetexception unable to connect to the url specified".
Actualy the url is a valid xml url "http://adobetes.com/f4iaw100/remoteData/employees.xml" and I can access it from broswer and the network connection is good. I tried another xml url, the same error still exist.
Could any one help me ?
have get any security related error?
if yes then check your crossdomain file.
