How to pass a Selected feature layer to Buffer services?

I am trying to pass my selected feature to geometry service and create a buffer. I am using ESRI example BufferSample with FeatureLayer_click_OnDemand. I am trying to make a parcel buffer for a mailing list. I can use the drawing tool and it works just fine but when I switch to select a parcel from the feature Layer and try to make a buffer it stop and give me no errors.
[HTML]
protected function bt_buffer_clickHandler(event:MouseEvent):void
   {
    var userInputPolyline:Array = fLayer.selectedFeatures;

    geodesicBuffer.geometries = [userInputPolyline];
    geodesicBuffer.distances = [ distance ];
    geodesicBuffer.unit = unit;
    geodesicBuffer.outSpatialReference = map.spatialReference;
    geodesicBuffer.geodesic = true;
    geodesicBuffer.unionResults = true;


    geometryService.buffer(geodesicBuffer, new AsyncResponder(geodesicBufferCompleteHandler, esriService_faultHandler, { userBufferType: 'geodesic' }));
   }[/HTML]
