Hi all I am trying to center my labels below my image inside my VGroup. The labels are align to left now and it seems like HorizontalAlign is not working on spark component. Anyone knows how to fix it? Thanks a lot.

        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:VGroup width="800">

        <mx:Image source="images/big/city1.jpg"/>
        <s:Label text="test1" horizontalCenter="0" /> //doesn't work....:(
        <s:Label text="test2" />


    </s:VGroup>
