How can i use RemoteObject without mxml?

Question

  hi:
   in my flex project , i use blazeds + puremvc , so i want to put my business code in actionscript as proxy to communicate with java code, the proxy code like :
public function requestServer(page:PageInfo):void{
   userServiceRM = new RemoteObject();
   userServiceRM.destination="userService";
   userServiceRM.getsimpleList();
   var pageResult :Object= userServiceRM.getsimpleList.lastResult;
   sendNotification(UserStartupCommond.USERLIST_GOT,pageResult );
but i have a problem that pageResult is a  null value .(the Configuring and the server side have no problem .)
how can i use RemoteObject without mxml?
 thanks.

Hi. Remote object calls are asynchronous so you can't access the result immediately after making the call. You need to wait until the server returns the result. There are a couple ways to set this up. Probably the easiest thing to do is to add an event listener that will be called when the result comes back from the server. Here is what that would look like.
public function requestServer(page:PageInfo):void {
userServiceRM = new RemoteObject();
userServiceRM.destination="userService";
userServiceRM.addEventListener("result", resultHandler);
userServiceRM.addEventListener("fault", faultHandler);
userServiceRM.getsimpleList();
public function resultHandler(event:ResultEvent) {
var pageResult :Object= userServiceRM.getsimpleList.lastResult;
sendNotification(UserStartupCommond.USERLIST_GOT,pageResult);
public function faultHandler(event:FaultEvent) {
//handle remote object fault
Look at the RPC Components section of the BlazeDS Developers guide for more information about using the RPC components. Hope that helps.
