When you specify a RelayResponder object for a service, results for all service functions are
relayed to the specified result and fault handling methods, which you must provide.

Using PendingCall and RelayResponder objects for a specific service function

After the Flash client application calls a service function, it does not stop executing to wait for the
return value; it continues to execute and specify which methods will handle the result or the fault
condition that the service function returns.
A call to a service method immediately returns a PendingCall object, which has a
property. You can handle the result and fault outcomes for each service method by creating an mx.

and the RelayResponder class in Flash Remoting ActionScript Dictionary Help.

Using the ResultEvent class

A successful call to a service function returns a ResultEvent object as an argument to the result
handling method. The ResultEvent object contains a
