Error handling mouse clicks in Treemaps

Flow
1

Hi,

I’m using the Charts add-on TreeMap. I’m trying to add a PointClickListener, however when I click on the TreeMap I get the following exception. Is this a known issue. It appears to fail decoding the yValue field of the object (which isn’t there, the xValue is, but not the yValue). I’m using Vaadin 7.5.8, and charts 3.0.0-alpha1.

Cheers,

Ray.

Hi, I also get the same error. Have you found away around it ? by using addChartClickListener ?

Hi - not yet - I’ve raised a ticket https://dev.vaadin.com/ticket/19350 - but unfortunately as yet I can’t recreate it in a simple example, it happens in our framework, but I can’t extract that out to a reproducible example.
