Flex 3.4 and FMS 3.5.1 - Problem sending ByteArray on RTMP call

Question

Hello, I installed a FMS 3.5 on my machine and created a new application with main.asc like this :

    application.onAppStart = function()
{
    /* Allow debugging */
    this.allowDebug = true;
}

//Client is connected
application.onConnect = function( client )
{

    //Accept the connection
    application.acceptConnection( client );

    client.allo = function(o) {
        trace("test : " + o ) ; 
        trace("length : " + o.length ) ; 
        trace("objectEncoding : " + o.objectEncoding ) ; 
        return o ;
    }

}

//Client disconnected
application.onDisconnect = function( client )
{
    //Trace on the FMS Application console
    trace( client+" is disconnected" );
}

This code prepare a function I call with my flex application, named "allo" and it returns the same byteArray in response.

The flex code is :

var anotherArray:ByteArray = new ByteArray();
                anotherArray.objectEncoding = ObjectEncoding.AMF3;
                anotherArray.writeObject(new String("foo"));
                nconn.call(func, echoResponder, anotherArray);

As a result, I get an empty ByteArray with only length,encoding, endian and position parameters. And a tcpdump trace shows that the ByteArray is empty.

So I wonder if it's only a pointer which is sent, or maybe I misconfigured something.

Do you know a way to investigate further or solve this ?

Thanks for any help,
