platform-core error handling in event handlers

[Göran Ehrsson]

Hi,

I recently started to use events with the platform-core plugin and it's a joy to use! (compared to spring-events).

But... when an exception is thrown in a event handler/subscriber, it is silently ignored. Nothing shows up in logs, etc.

Is this by design? Is there a log category I need to configure to see the exception?

I know I need proper error handling in my event handlers, but it's very easy to miss problems when exceptions are silently ignored.

Regards

Hi

Thank you for your feedback !

No its not by design. There is a problem somewhere, can you try to add an on onError parameter to your event call (or your DSL event definition) ?

events = {

  '*' onError:{ println it }

}

or 

event topic:'test', data:data, onError: { println it }

Cheers
