Hello! I use example code from Flex tutorial:

<?xml version="1.0" encoding="utf-8"?>
<!-- Simple example to demonstrate the Spark DropDownList control -->
<s:Application xmlns:fx=""



            import mx.collections.ArrayCollection;

            public var myDP:ArrayCollection = new ArrayCollection(
                [ {product:"Flex", price:100},
                  {product:"Air", price:200},
                  {product:"Catalyst", price:300},
                  {product:"FlashBuilder", price:400} ]);

            private function updateSelection(e:IndexChangeEvent):void
                currSel.text = "Current Product = " + myDDL.selectedItem.product;
                currPrc.text = "Price = $" + myDDL.selectedItem.price;

    <s:Panel width="75%" height="75%" title="My DropDownList Example"

        horizontalCenter="0" verticalCenter="0">

        <s:VGroup left="10" right="10" top="10" bottom="10">

            <!-- Text components used to display current selection and price -->
            <s:Label id="currSel" text="Current Product = -"/>
            <s:Label id="currPrc" text="Price = $ -"/>

            <!-- DropDownList will call the updateSelection function when the
            selectionChanged event is dispatched -->
            <s:DropDownList id="myDDL" prompt="Select One"

                width="200" dataProvider="{myDP}"






This get me one error:

Severity and Description    Path    Resource    Location    Creation Time   Id
Could not resolve <s:Application> to a component implementation.    LABAMENU/src    LABAMENU.mxml   line 4  1370013049718   77
