Vaadin Charts 3.1 PointClickListener not working
After moving from charts 2.0 to 3.1 the following code does not work anymore:
Chart result = new Chart(ChartType.PIE);
result.addPointClickListener(new PointClickListener() {
@Override
public void onClick(PointClickEvent event) {
// my code
}
});
This used to work, so I can capture clicks in the pie chart. But now clicking on the chart results in this error in my tomcat log:
Jul 18, 2016 10:24:25 PM com.vaadin.server.communication.ServerRpcHandler parseServerRpcInvocation
WARNING: Ignoring RPC call to com.vaadin.addon.charts.client.ui.ChartServerRpc.onPointClick in connector com.vaadin.addon.charts.Chart(47) as no RPC implementation is registered
I am doing something wrong or is this a bug?
Hi Sascha,
Thank you very much for the quick reply. You are right, that was indeed the problem.
Cheers,
Harm
