U need to make two different handlers..
1) for the login Request .. coming from the login form...
2) for the result coming back from the http service..
U have declared both with the same name..
First of all change that..
U cant directly access the loginUser and pass..
either u have to call _start.loginUser.text...
or as per ur code.. ( since you are passing the username and password
through the loginEvent)
inside the
loginRequestHandler(event:LoginEvent):void
{
trace( event.username);
trace(event.password);
}
