LCDS Fetching a single row

Hello guys,

i need your help,

im doing Model Driven Development and want to know if there is a way to call a service method Synch  NOT Asynch.

All the calls are Asynch.

"

               var funcionarioToken:AsyncToken = new FuncionarioService().getAll();

            funcionarioToken.addResponder(new AsyncResponder(
                function (event:ResultEvent, token:Object=null):void
                {
                    _funcionarioInput.dataProvider = event.result;
                },
                function (event:FaultEvent, token:Object=null):void
                {
                    Alert.show("Associated service call failed: " + event.fault.faultString, "Error");
                }));

"

Is  there a way to define the return type of the service calls, for exemple  , if i want to fetch a single row from a database table by its ID how  would i do?

var myVar:MyObjectType =  event.result as MyObjectType; ??????

regards
