Multiple asynchronous responses

Question

I am attempting to use two RemoteObject requests at the same
time. I want to allow the user to continue using the screen after
either one of these requests has returned, and to just notify them
when the second one arrives. I am trying to do this without FDS.
However, though I can send both messages asynchronously the user is
not able to use the interface until both calls have completed. One
of the operations completes immediately, and the other one waits
for 10 seconds before completing. But I do not receive a response
from the first operation until the second operation has completed.
The Java methods on the server are being executed in series, and
therefore the method that returns immediately is waiting for
completion of the method that waits 10 seconds. The AS methods on
the client both return from calling the remote object operation
very quickly, obviously. I am currently using a RemoteObject
instances to invoke the operations on the server.

Answer 1

I am so sorry, but I still do not understand how to set the
endpoint. Here are the lines from my AS class:
public class JSINotifierList extends ArrayCollection {
private var remoteObject: RemoteObject;
public function JSINotifierList(dao: String) {
remoteObject = new RemoteObject();
remoteObject.destination = dao;
remoteObject.concurrency = "last";
remoteObject.addEventListener(ResultEvent.RESULT,
handleResultEvent);
remoteObject.addEventListener(FaultEvent.FAULT,
handleFaultEvent);
} // JSINotifierList()
public function register(... args): void {
var operation: AbstractOperation =
remoteObject.getOperation("register");
operation.send(args);
} // register()
... result and fault handling is here ...
Just in case it is important, here is the code from the mxml
file:
[Bindable] private var dtoList: JSIDTOList;
[Bindable] private var notifierList: JSINotifierList;
private function appCreationComplete(): void {
notifierList = new JSINotifierList("JSIFlexNotifier");
notifierList.register([]);
dtoList = new JSIDTOList("JSIFlexDAO");
dtoList.fill(["<Pars id='all'/>", 3]);
} // appCreationComplete()
I don't know whether any of this makes sense from a Flex
perspective! I am calling the "register" function from this class
so that if the server wants to notify the client of something
(i.e., "push" data to the client) then it will respond to the RPC
call. I have other classes that provide data collections for the
actual core work of the application. But I can't figure out how to
get the other classes to return from RPC calls without returning
from the RPC call to the JSINotifierList object. I could, of
course, cancel the call to the JSINotifierList whenever I want to
make a request to another destination, and then requeue the request
to the JSINotifierList object when that call returns. But I was
hoping to have both methods running concurrently in the web server.
Again, I appreciate your responses, and I am quite content
for you to tell me to "go away and learn more about Flex" before
attempting to do this!
