Why filterData() on a Menu does mute the addItemClickHandler() behavior?

-> It is a cast problem

Here is a how to handle this:

grid.addRowContextClickHandler(new RowContextClickHandler()
{
    public void onRowContextClick(RowContextClickEvent event)
    {
        final ListGrid listGrid = (ListGrid) event.getSource();
        Criteria criteria = new Criteria();
        for (ListGridRecord rec : listGrid.getSelection())
            criteria.addCriteria("ID", rec.getAttribute("ID"));
        final Menu contextMenu = listGrid.getContextMenu();
        contextMenu.filterData(criteria, new DSCallback()
        {
            public void execute(DSResponse response, Object rawData, DSRequest request)
            {
                Record[] data = response.getData();
                MenuItem[] items = new MenuItem[data.length];
                int i = 0;
                for (Record rec : data)
                    items[i++] = (MenuItem) rec;
                contextMenu.setItems(items);
            }
        });
    }
});
