Hello Martin, WicketEndpoint#onError is being called "*ERROR* 05-01 16:10:21.740 o.a.w.p.w.j.WicketEndpoint:100 [EventExec-e2-t9] - An error occurred in web socket connection with id : 10"
The problem WebSocketBehavior#onError is not being called So my application doesn't get notified the connection has been closed .... :( On Fri, 1 May 2020 at 17:12, Martin Grigorov
