I've added a ChartListener to a StackedBarChart, but it's chartClicked and handleEvent methods are never invoked. Is it possible to register a ChartListener with a StackedBarChart for the purpose of handling chart events?

Code Sample

public
class LayoutTest implements EntryPoint {

publicvoid onModuleLoad() {
RootPanel.get().add(
new VerticalStackedChart());
}

class VerticalStackedChart extends ContentPanel {

public VerticalStackedChart() {
setBorders(
false);
setBodyBorder(
false);
setHeaderVisible(
false);
setHeight(500);
setWidth(400);
}

@Override

protectedvoid onRender(Element parent, int index) {
super.onRender(parent, index);
XAxis xAxis =
new XAxis();
xAxis.setMin(0);
xAxis.setMax(1);
xAxis.setSteps(1);

YAxis yAxis =
new YAxis();
yAxis.setMin(0);
yAxis.setMax(800);
yAxis.setSteps(100);

StackedBarChart barChart =
new StackedBarChart();
barChart.setTooltip(
"#key# - #val#");

List<StackedBarChart.StackValue> data =
new ArrayList<StackedBarChart.StackValue>();
data.add(
new StackedBarChart.StackValue(100, "#AF1E2D", "Text 1"));
data.add(
new StackedBarChart.StackValue(200, "#006B54", "Text 2"));
data.add(
new StackedBarChart.StackValue(400, "#003F87", "Text 3"));
barChart.addStack(data);

data =
new ArrayList<StackedBarChart.StackValue>();
data.add(
new StackedBarChart.StackValue(200, "#AF1E2D", "Text 1"));
data.add(
new StackedBarChart.StackValue(400, "#006B54", "Text 2"));
data.add(
new StackedBarChart.StackValue(100, "#003F87", "Text 3"));
barChart.addStack(data);

ChartModel model =
new ChartModel();
model.setXAxis(xAxis);
model.setYAxis(yAxis);
model.addChartConfig(barChart);

Chart chart =
new Chart("resources/chart/open-flash-chart.swf");
chart.setChartModel(model);

add(chart);

barChart.addChartListener(
new ChartListener(){

@Override

publicvoid chartClick(ChartEvent ce) {
// TODO Auto-generated method stub

super.chartClick(ce);
Window.alert(
"Chart Click");
}

@Override

publicvoid handleEvent(ChartEvent ce) {
// TODO Auto-generated method stub

super.handleEvent(ce);
Window.alert(
"Chart Event");
}});
}
}

}
