> When items are removed from a ListButton's data source,  the list button's skin receives the removal notification and updates the selection before the internal ListView gets the removal notification. As a result, when the internal list view gets the removal notification, its selection state is incorrectly updated again, causing the selection to be cleared. 
> The following sample code demonstrates the problem:
> <Window title="ListButton Selection Test" maximized="true"
>     xmlns:bxml="http://pivot.apache.org/bxml"
>     xmlns="org.apache.pivot.wtk">
>     <windowStateListeners>
>     function windowOpened(window) {
>         listButton.getListData().remove(0, 2);
>     }
>     </windowStateListeners>
>     
>     <BoxPane orientation="vertical">
>         <ListButton bxml:id="listButton" listData="[1, 2, 3, 4]" selectedIndex="3"/>
>     </BoxPane>
> </Window>
> This problem can probably be solved by adding a ListButtonItemListener interface that proxies model change events after ensuring that the list button has a consistent internal state (as is already done in ListView, TableView, Spinner, and TreeView).
