Jason, By the look of it, you will never receive an onResult for your getUserListResult ... it's a simple Object and no Method onResult exists for that class that I know of ...
What are you using to make your webservice calls ? are you using Flash Remoting ? if so you should use the responder to handle the result. import mx.remoting.Service; import mx.remoting.PendingCall; import mx.rpc.RelayResponder; import mx.rpc.FaultEvent; import mx.rpc.ResultEvent; var myService:Service = new Service( gatewayUrl , null , serviceName , null, null ); var pc:Pendingcall = new PendingCall(); pc.relayResponder(myService, "handleResult", "handleError"); well I can't really remember from the top of my head, I'll need to look it up from home, but this is somewhat how you can know when the data has arrived from the webservice. So your class be ends up beeing a Service caller, you can make it a Singleton and use it to fetch different services from your gateway. You should definitely look into the ARP framework (or other similar projects) ... that's how I learned how to best use Design Paterns :) after 2 projets with it, you'll definitely understand :) HTH !

Alain, Been following your suggested method, it's great, and everything works as advertized, except can't get wsResulthandler to fire once the Webservice data is received. Also, how do I send the data from the comboBox change event through to the getWsData function? I need to know the data from the selected item in the combobox, as that is a parameter I sent to the webservice to get the data. I hard coded it a number for now, but it doesn't work because of the first problem. Here is a snippet of the code in "Class B" function getWSdata(lobDbId:Number) { var getUserListResult:Object = new Object(); getUserListResult = root_mc.generatorWS.GetUserList(1) //lobDbId); getUserListResult.onResult = Delegate.create(this, wsResulthandler); } function wsResulthandler(data) { _level0.traceMsg("WS Result recieved.") this.dispatchEvent({type:"webServiceResult", newData:data}) } Did I set that up right?
