</s:Transition>
</s:transitions>

<s:actionContent>
<s:Button label="large" click="currentState='large'" />

</s:actionContent>

<s:SpinnerListContainer id="slc"
horizontalCenter="0" width.large="90%" width.small="50%"
verticalCenter="0" height.large="90%" height.small="50%">
<s:SpinnerList width="100%" height="100%">
<s:NumericDataProvider />
</s:SpinnerList>
<s:SpinnerList width="100%" height="100%">
<s:NumericDataProvider />
</s:SpinnerList>
<s:SpinnerList width="100%" height="100%">
