Hi, I’m trying to use console light option in Gatling.conf :

console {  
light = true # When set to true, displays a light version without detailed request stats  
}

and saw next exception:

[ERROR] [09/19/2014 07:50:04.761] [GatlingSystem-akka.actor.default-dispatcher-2] [akka://GatlingSystem/user/$2] io.gatling.core.util.StringHelper$anon$1 cannot be cast to io.gatling.core.result.writer.ConsoleSummary$anon$8

Could someone, please, help me - it’s a bug or I need to add some other option to use “console light”?

Thank you so much!

Hi Daria,

This is a bug: [https://github.com/gatling/gatling/issues/2219](https://github.com/gatling/gatling/issues/2219)

I’ve fixed it and it will be shipped in RC6 (probably on monday).

Thanks for reporting!

Stéphane
