 [Bindable]
 public var listaId:Number=0;
 [Bindable]
 public var listaArray:Array;

            {
                var itens:ArrayCollection=dg.dataProvider as
ArrayCollection
                if (dg.selectedItem != null){
                 for (var i:int=0; i < itens.length; i++){
                     if (dg.selectedItem.selected == true){
                            listaArray=[dg.selectedItem.data];
                        Alert.show(dg.selectedItem.data);
