-----------------------------
> Drop-down list view in list button does not retain selection state when model
> data changes

> Key: PIVOT-594
> URL: https://issues.apache.org/jira/browse/PIVOT-594
> Project: Pivot
> Issue Type: Bug
> Reporter: Greg Brown
> Assignee: Greg Brown
> Priority: Minor
>
> 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).
