Hello, everybody!
I recently upgrade my Vaadin-Charts from 1.1.9 to 3.3.1, PointClickEvent doesn't work anymore, show error as follow:
com.vaadin.server.communication.ServerRpcHandler parseServerRpcInvocation
WARNING: Ignoring RPC call to com.vaadin.addon.charts.client.ui.ChartServerRpc.onChartClick in connector leo.snowball.view.ChartBase(134) as no RPC implementation is registered
my vaadin is 7.7.7, and after upgrading Chats to 3.3.1, I've recompile vaadin widgetset successfully.
any idea? thanks.
