I'm experiencing a problem using amfphp and flash. See the below code.

I have the RegisterUser function being called by a submit button. The function
successfully completes, and I get the expected amf response returned. But I
only know I get it returned because I'm using a packet sniffer, as there is no
trace from RegisterUser_result. The RegisterUser_result function is not fired,
UNLESS I move all the code from the RegisterUser function out of the function
and have it fire at runtime. So I can only assume that when RegisterUser_result
is called by the RelayResponder, it can't be found. But why not? And why don't
I get an error? I can call RegisterUser_result directly from inside the
ResultUser function, so the function scope should be fine.

function RegisterUser()
{
trace("in register user");
var register_service:Service = new
Service(_global.gateway_url,null,"Register", null,null);
register_service.connection.setCredentials(_global.amfphp_admin,
_global.amfphp_pass);
var ru:PendingCall = register_service.RegisterUser(txtEmail.text,
txtPassword1.text, txtPassword1.text, listAge.value, listCountry.text);
ru.responder = new RelayResponder(this, "RegisterUser_result",
"GenericFault");
}

function RegisterUser_result(re:ResultEvent)
{
trace("in result");
}

Thanks for looking!
