Как вызвать метод, который имеет единственный аргумент типа long для использования BlazeDS?

Я не могу вызвать метод, который имеет только аргумент типа "long" для использования Adobe BlazeDS?

Вот оно.

[Flex] 

var ro:RemoteObject = new RemoteObject();
ro.destination = "objectService";
ro["getById"].send(3107);

[Java] 

public class ObjectServiceImpl implements ObjectService {
    public ObjectDomain getById(long id) {
       ・・・
    }
}

Итак, эта ошибка произошла. 

flex.messaging.MessageException: Cannot invoke method 'getById'. 3,107
arguments were sent but 1 were expected.

Попробуйте следующее: 

        //The way you defined the RemoteObject
        var ro:RemoteObject = new RemoteObject();
        ro.destination = "objectService";

        //The id variable
        var id:Number = 3107;
        //The Operation to send over the RemoteBoject
        var getByIdOperation:Operation = new Operation();
        //Name of the method on the server side
        getByIdOperation.name = "getById";
        //The argument in this case the long 3107 ( var id:Number= 3107)
        getByIdOperation.arguments = [id];
        //The method to handle the result if needed
        getByIdOperation.addEventListener(ResultEvent.RESULT, getByIdHandler)
        //Send the operation through the RemoteObject(ro)
        ro.operations = [getByIdOperation];
        getByIdOperation.send();

java.lang. Long в ActionScript-3 представлен как Number . Пример метода, вызываемого, когда удаленный вызов получает результат 

    private function getByIdHandler(event:ResultEvent):void
    {
        myObject = event.result as ObjectDomain;
    }
...
