I doubt this requires setting up a special JSF 1.2 build of component-showcase, since it looks like an application problem.

But anyways, the issue is that if you bring up the Charts page, and change to either a 2D pie chart or 3D pie chart, then the first time you click on the chart image map, it will throw the following exception. Subsequent clicks seem to be ok.

org.krysalis.jcharts.chartData.ChartDataException: There is not an one to one mapping of 'Paint' Implementations to 'data items'.
