Bar chart drilldown - not working

Hi
I have tried to follow the examples on demo.vaadin.com/charts but I can't make the drilldown work. I have also tried switching to column chart but it still doesn't work. Nothing happens when I click the bars (no exceptions either)

Here is my code (the drilldown series is hard coded just to try to make it work):

Chart chart = new Chart(ChartType.BAR);
chart.getConfiguration().disableCredits();
PlotOptionsBar plotOptionsBar = new PlotOptionsBar();
plotOptionsBar.setCursor(Cursor.POINTER);
chart.getConfiguration().setPlotOptions(plotOptionsBar);

YAxis yAxis = new YAxis(); yAxis.setType(AxisType.CATEGORY);
yAxis.setTickmarkPlacement(TickmarkPlacement.ON);
yAxis.setMin(0);
yAxis.setFloor(0);
yAxis.setStartOnTick(true);
yAxis.setEndOnTick(true);
yAxis.setCategories(optimalPathCodes.toArray(new String[optimalPathCodes.size()]));
yAxis.setTitle("");


Tooltip tooltip = new Tooltip();
tooltip.setAnimation(true);
tooltip.setUseHTML(true);
tooltip.setHeaderFormat("<strong>{point.key}</strong>");
tooltip.setPointFormat("");
tooltip.setFooterFormat("");
chart.getConfiguration().setTooltip(tooltip);
chart.getConfiguration().getLegend().setEnabled(false);

DataSeries series = new DataSeries();
for (InitiativePerformanceDPO dpo : activeInitiativesAtTime) {
 String initiativeCaption = dpo.getProcessSubject() + " (" + dpo.getStatusAtTime().value() + ") - " + dpo.getLastOptimalPathStatusAtTime().value();
 DataSeriesItem dataSeriesItem = new DataSeriesItem(initiativeCaption, dpo.getOptimalPathStatusIndex());

 Color barColor;
 if (dpo.getStatusAtTime().incident()) {
   barColor = new SolidColor(FasthiStyle.RED_COLOR);
 } else if (dpo.getStatusAtTime().equals(dpo.getLastOptimalPathStatusAtTime())) {
   barColor = new SolidColor(FasthiStyle.GREEN_COLOR);
 } else {
   barColor = new SolidColor(FasthiStyle.YELLOW_COLOR);
 }
 dataSeriesItem.setColor(barColor);

 DataSeries drillSeries = new DataSeries("Swarco details");
 String[] categories = new String[]{"2016-11-01", "2016-11-16", "2016-12-04", "2016-12-16"};
 Number[] data = new Number[]{1, 0, 2, 0};
 drillSeries.setId(initiativeCaption);
 drillSeries.setData(categories, data);
 series.addItemWithDrilldown(dataSeriesItem, drillSeries);

 chart.getConfiguration().getxAxis().addCategory(dpo.getProcessSubject() + " (" + dpo.getStatusAtTime().value() + ")");
}


chart.getConfiguration().addSeries(series);
chart.setHeight(30 * activeInitiativesAtTime.size(), Sizeable.Unit.PIXELS);

return chart;

I got your example working. Only difference I have is that my InitiativePerformanceDPO is some hard coded stuff I created to test.

Ok. That's weird. I have to go over it again to see what I have missed.

Johannes Häyry: I got your example working. Only difference I have is that my InitiativePerformanceDPO is some hard coded stuff I created to test.

You haven't done anything else? I still can't get it to work. So frustrating
