In an ace:chart (pie chart) component in view page populated with String-Long type of key-value pairs. The chart is rendered fine, but when I clicking on a slice invoking the method registered in selectListener property, NumberFormatException is thrown saying that the label cannot be cast to int.

This mechanism resides in the ChartRenderer.processSelections API method when the seriesIndex and pointIndex variables are attempted to create.

private void processSelections(Chart chart, String[] select) {
int seriesIndex = Integer.parseInt(select[0]);
int pointIndex = Integer.parseInt(select[1]);
chart.queueEvent(new SeriesSelectionEvent(chart, seriesIndex, pointIndex));
}

the select[0] and select[1] values should first be checked for type of Object and then cast accordingly, rather than assumed it's an Integer value. (Support Case would like to be able to use a String for label of pie chart)
