Debug Information

Caused by invalidate during setType

Charts.invalidate() line: 2530 Charts.invalidate() line: 2530 PlotData.onChange(OptionDataEvent) line: 367 Chart(Optionable).fireEvent(OptionDataEvent) line: 92 Chart(Optionable).fireEvent(EventType, String, Object, DeferredCall) line: 74 Chart(Optionable).fireEvent(EventType, PlotAttribute, Object) line: 56 Chart(Optionable).setAttr(PlotAttribute, Object, T) line: 204 Chart.setType(String) line: 1323 Charts.setType(String) line: 818 

Invalidate contains 

_drilldownLevels.clear()

Next call to Charts.services with the Drill down command will go through:

				if (_drilldownLevels == null) {
					_drilldownLevels = new LinkedList<Series>();
					_drilldownLevels.addFirst(evt.getSeries());
				}
 

Since drilldownLevels is not null, it doesn't go in this conditional statement.

SInce it doesn't go in the conditional statement, the root level is never added to the drilldownLevels

When the drill up command is triggered, drill up removes the first entry in the drilldowns

			if (ChartsEvents.ON_PLOT_DRILL_UP.equals(cmd)) {
				_drilldownLevels.removeFirst();

 At this point, the drilldowns should contain (at least)  the last drill level and the root level.

Since the root level was never added, the _drilldownLevels is empty after this step, causing following line's 

_drilldownLevels.getFirst();

to trigger a no element exception
