Strange. Any chance it is your dynamic listener manipulation? That is the only odd thing I see. (why are you doing that, by the way?) I mostly use HTTPService, and had an app the fired off over 90 calls on init and never lost any of them. I used a single HTTPService instance and a single result handler. I even counted the calls on send(), and decremented the count in the handler to know when they were complete.

I have some back-to-back web service calls that don't seem to work when I call them as: ws.GetMusicians(); ws.GetInstruments(); ws.GetProducts(); but if I call them in a forced-sequential pattern, they all work fine. (The web server is a .NET service that returns ArrayCollections). My mxml file calls my GAWebService tier: var ws = new GAWebService(); The GAWebService tier handles the transaction with the web service: public function GetInstruments( ):void { ws.addEventListener( ResultEvent.RESULT, instrumentsHandler ); var callToken:AsyncToken = ws.GetInstruments(); callToken.marker = "GetInstrumentsCall"; } private function instrumentsHandler( event:ResultEvent ):void { ws.removeEventListener( ResultEvent.RESULT, instrumentsHandler ); var callToken:AsynchToken = event.token; var resultCollection:ArrayCollection = (event.result AS ArrayCollection); switch( callToken.toString() ) { case "GetInstrumentsCall": GADataModel.getInstance().Instruments = resultCollection; break; etc. } } Again, if I force a sequence wherein the handler of one call makes the next webservice call in the series, I get all of the results back, but if I leave it to the "asynch-ness" of the webservice, I only get a couple of the calls completed. Does the Flex WebService queue up the calls or do I have to write some sort of call queue class in order to manage the asynchronous traffic?
