Event listener troubles

I'm rather new to flash builder, as I am editing an app that was contracted made offshore.  I have added a new service but my listener never hits,  I used fiddler to see that it successful querys the webservice but the success (or failure) events never fire. 

protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void

{

var serviceManager:Refer_EarnServiceManager = new Refer_EarnServiceManager();

serviceManager.addEventListener(Refer_EarnWebServiceEvent.RECOMMENDED_ BUSINESS_SERVICE,onRecommendedBusinessSuccess);

serviceManager.addEventListener(FaultEvent.FAULT,onRecommendedBusiness Fail);

serviceManager.getRecommendedBusinesses( BusinessVO(data).intBusinessID); // BusinessVO(data).intBusinessID

showBusy();

}

private function onRecommendedBusinessSuccess(event:Refer_EarnWebServiceEvent):void

{

hideBusy();

//AppModel.getInstance().recommendedbusinessList = event.result

var arrcol:ArrayCollection = Refer_EarnWebServiceParser.parseRecommendedBusinessResult(event.resul t);

appModel.recommendedbusinessList = arrcol;

if(arrcol.length>1)

{

// navigator.pushView(Refer_EarnChooseBusiness2,arrcol);

hideBusy();

}

else

{

// navigator.pushView(Refer_EarnMainView,arrcol[0] as BusinessVO);

hideBusy();

}

}
