Hi All,

I have extended the StringValidator class in order the create a username validator. When a new user is being registered, the username is validated on the server to check if it exists.

The code is not throwing errors and i know the remoteobject calls work. The push sets the message, but the problem is that the result is not returned.

Is the flow correct?

public class PosUsernameValidator extends StringValidator {
          
          private var userServiceRO:RemoteObject = new RemoteObject();
          private var validatorResults:Array = new Array();
          
          public function PosUsernameValidator(){
               super();
               userServiceRO.destination = UserService;
               userServiceRO.getUserByUserName.addEventListener(result, getUserByUserNameRH);
               userServiceRO.getUserByUserName.addEventListener(fault, getUserByUserNameFH)
          }
          
          override protected function doValidation(value:Object):Array {
               validatorResults = super.doValidation(value); 
               return doForUserName(value);
          }
          
          private function doForUserName(value:Object):Array{
               userServiceRO.getUserByUserName(String(value));
               return validatorResults;
          }
          
          private function getUserByUserNameRH(r:ResultEvent, t:Object = null):void{
               var user:User = r.result as User;
               if(user!=null){
                    validatorResults.push(new ValidationResult(true, null, Username error,Username already taken!));
               }
          }
          
          private function getUserByUserNameFH(f:FaultEvent, t:Object = null):void{
               Alert.show(ObjectUtil.toString(f));
          }
          
     }
