Chart ItemSelectEvent series and item index possibly wrong

Hi all,

I am running a test based on the sample provided on and added an itemSelectListener as follows:

with the following backing bean method:
public void itemSelect(ItemSelectEvent event) {
     System.out.println(event.getItemIndex() + " " + event.getSeriesIndex());

The thing is it does not matter if I click on boys or girls on 2004 data it always prints:
09:07:26,351 INFO [STDOUT] 0 0
The same happens when I click on any series of 2005 it always prints:
09:07:46,617 INFO [STDOUT] 1 1

Shouldn't it be printing 0 0 and 0 1, respectively, when I click on boys 2004 and girls 2004 and also print 1 0 and 1 1 if I had clicked on the same series order but on 2005?

best regards,
Rafael Ribeiro

Hi Rafael,

It seems to be a bug, can you please create an issue in our issue tracker and post the link here.

This seems quite easy to fix as well.

Thank you.

It should be trivial yes, itemSelectListener in charts.js file is the key. Problem is that on javascript side, I guess we are sending the wrong value.

I guess some js optimizer is run on charts.js so the change on the jar for the release is:


Or in case of charts.js on sources jar:
params['seriesIndex'] = event.index;

params['seriesIndex'] = event.seriesIndex;

Yes, in production all js are compressed.

Can you create an svn patch for this and attach to the issue.
