Hi,
One difference between Royale and Flex is that Royale cannot detect types with
different access methods at runtime, so you will have to modify your code
slightly to tell the compiler how to generate the access code.
IOW: if you write:
remoteObject.GetVersion.addEventListener("result",GetVersionHandler);
Then in Flash, each access (get the property “GetVersion” from “remoteObject”,
get the function “addEventListener” from “GetVersion”) is handled by Flash and
it knows that remoteObject is a property so it can call “getProperty” and then
the runtime examines that, determines it is an Operation and then knows to its
call “addEventListener”.
In Royale, the JavaScript runtimes don’t know about Proxy (at least in this
version of Royale). The compiler knows that remoteObject is a Proxy so it
calls getProperty, but compiler cannot know the result is an Operation at
compile time and the JS runtime doesn’t care anyway, so Royale’s compiler
currently assumes that the result of a getProperty is another Proxy because
there might be nested trees of ObjectProxys in data structures.
So, the answer is to modify the code to indicate to the compiler what the
result of the getProperty is:
(remoteObject.GetVersion as
Operation).addEventListener("result",GetVersionHandler);
You may need to import mx.rpc.remoting.Operation;
HTH,

Subject: RemoteObject y addEventListener SyntaxError
[cid:[email protected]]
Hello,
I am migrating a wrapper between my app. flex and the backend (AMF - FluorineFX
- .net). (Apache Flex - works ok)
I cannot add the listener of the result of any method. I compile well but when
I run it gives me an error.
This is the wrapper ...

}
channelSet.addChannel(channel);
remoteObject = new RemoteObject(modelo.destination);
remoteObject.requestTimeout = -1;
remoteObject.showBusyCursor = true;
remoteObject.source = "flexfx.wpl.wplNet";
remoteObject.channelSet = channelSet;
this.model = modelo

I have no idea what happens, can you give me a hand?
