[flexcoders] Scale 9 not applied to vboxes?

[Austin Kottke]

Hi, Im setting a scale 9 that is being set to a vbox. The vbox itself is 
not doing any scale 9 even though I have set the background image style 
to the the vbox.

<mx:VBox styleName="LeftPanel" />

.LeftPanel {
    backgroundImage: Embed(source="../img/leftPanelBg.gif",
                scaleGridLeft="29",
                scaleGridTop="26",
                scaleGridRight="270",
                scaleGridBottom="32");
}

The width of the vbox is not working correctly because it shows the 
background without scaling the image.

What is the problem here?
