Creating a s:list via AS3 doesn't show the data?

Question

If I do something like this below the list shows up on the screen but the items in the dataprovider don't show up.  If I throw the List in via MXML tags it shows up fine.  Any suggestions?  And yes, I know the data is there as it works when using an MXML version of the list.
                var thirdList:List = new List();
                thirdList.dataProvider = someDataProvider;
                thirdList.useVirtualLayout = true;
                third.addElement(thirdList);
TIA

  No it isn't empty.  I think States are broken.  If I do the following:
<s:HGroup id="listHolder" width="100%" height="100%">
        <s:List id="initialList"
                 width="150" height="100" maxHeight="100"
                 change="onInitialListSelection(event)" />
        <s:List id="secondList"
                 visible.showSecondListState="true"
                 visible="false" width="0" width.default="0" width.showSecondListState="150"
                 height="100" maxHeight="100" width.showThirdListState="150"
                 change="onSecondListSelection(event)" />
        <s:List id="thirdList"
                excludeFrom="default" "
                dataProvider="{someHardCodedDataIthatIsNeverEmpty}"
                change="onSecondListSelection(event)" /> 
    </s:HGroup> 
When the thirdList is shown, meaning the state is not in default, the space where thirdList should show up expands like the s:List is there, but it visually isn't shown.
