Not receiving COMPLETE event in URLLoader

Question

Hi:
I'm querying a web application in a remote server through XML files and receiving answers in the same file format. Until now, sometimes I received a connection error:
Error #2044: Unhandled ioError:. text=Error #2032: Stream Error. URL: http://server/Services/startSesion.com
    at reg_jugadores_fla::MainTimeline/queryGQ()
    at reg_jugadores_fla::MainTimeline/reg_jugadores_fla::frame1()
When this occurs, trying to access the services through a web browser, there's a test page where you can try queries, returns a "500 Internal server error". I managed that problem adding a listener to catch the error:
xmlSendLoad.addEventListener(IOErrorEvent.IO_ERROR, catchIOError);
But since yesterday I can't connect anymore using Flash while it's possible to access the test page. I'm not able to talk to any support guy as the company is closed for vacations! I added listeners to try to know what's happening and this is the result in the output window:
openHandler: [Event type="open" bubbles=false cancelable=false eventPhase=2]
progressHandler loaded:154 total: 154
httpStatusHandler: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=200]
AFAIK, status=200 means OK but why the COMPLETE event isn't dispatched?. So, is there anything I can do or just wait until the tech guys return from the beach?
Thanks in advance
queryGQ(sessionURL,sessionQS);  // Start session
stop();
function queryGQ(url:String,qs:String):void {
var serviceURL:URLRequest = new URLRequest("http://server/Services/"+url);
serviceURL.data = qs;
serviceURL.contentType = "text/xml";
serviceURL.method = URLRequestMethod.POST;
var xmlSendLoad:URLLoader = new URLLoader();
configureListeners(xmlSendLoad);
xmlSendLoad.load(serviceURL);
function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.COMPLETE, loadXML);
dispatcher.addEventListener(Event.OPEN, openHandler);
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, catchIOError);
function openHandler(event:Event):void {
trace("openHandler: " + event);
function progressHandler(event:ProgressEvent):void {
trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
function securityErrorHandler(event:SecurityErrorEvent):void {
trace("securityErrorHandler: " + event);
function httpStatusHandler(event:HTTPStatusEvent):void {
trace("httpStatusHandler: " + event);
function ioErrorHandler(event:IOErrorEvent):void {
trace("ioErrorHandler: " + event);

Hugo,
View may not fire events. View may call method on other controller (component / custom) and this controller fires event.
You are absolutely right: in WD only instantiated controllers receives the event, event itself does not cause controller instantiation.
The only controller that is always instantiated is component controller.
Custom controllers instantiated on demand when their context is accessed or user-defined method called.
As far as view may not have externally visible context nodes and methods (you may not add view controller as required to other one and use nodes/methods of view), the only time when view is instantiated is when it get visible for first time.
To solve your problem, try the following:
1. Save event parameters to component controller context node element before firing event.
2. Create mapped node in target view and set node from controller as source.
3. In wdDoInit of target view insert the following code:
wdThis.<eventHandlerName>(
null, //no wdEvent
wdConext.current<NameOfMappedNode>Element().get<NameOfParamA>(),
wdConext.current<NameOfMappedNode>Element().get<NameOfParamB>(),
