Flex HTTPService Timeout handler

Question

my flex application sends a few concurent requests on startup. Sometimes it takes a lot of time to fetch them all so I've set them requestTimeout param to 5 secs. Additionally, I've defined a method that handles fault events. I'd like to resend a request when timeout occurs. It doesn't work though. Could you take a look at the code?

protected function fatalErrorOccuredInfo(event:FaultEvent):void
{
    // get the operation
    var operation:mx.rpc.http.AbstractOperation = mx.rpc.http.AbstractOperation(event.target);

    operation.url += "?t=" + new Date().getTime();
    operation.useProxy = false;
    //this should resend a request that caused timeout
    operation.send();

}

I check whether a new request is sent in Network Monitor but it doesn't show anything :-(

Any help would be much appreciated.

Answer 1

WebService class has a getOperation function which returns an AbstractOperation.

Use it with event.currentTarget.name

So it would be something like

var operation:mx.rpc.http.AbstractOperation = myWebService.getOperation(event.currentTarget.name);
operation.send();

I am pretty not sure but if operation.send() does not get to the result event, you might have to add an event listener for ResultEvent.RESULT

Answer 2

One problem I see is with this line

operation.url += "?t=" + new Date().getTime();

Every time you make a request you append "?t=" + new Date().getTime();
Although that shouldn't be your main issue it is a problem.

private var operationURL:String = "someurl.com/page.php";
private function loadOperation( ):void{
  var operation:mx.rpc.http.AbstractOperation = mx.rpc.http.AbstractOperation(event.target);
  operation.url = operationURL + "?t=" + new Date().getTime();
  operation.useProxy = false;
  operation.send();
}

private var retryCount:int = 0
protected function fatalErrorOccuredInfo(event:FaultEvent):void{
  // don't want it stuck in an endless loading loop
  // 10 count is more then enough 
  if( retryCount < 10 ){
    this.loadOperation( );
    ++retryCount 
  }
}

Also, If you have FireFox installed get an add-on called HTTPfox.
HTTPfox will show you all requests made from the browser
