Question about building custom RequestAction

[drewvella-dpg]

I followed the tutorial which teaches you to extend Gatling and essentially led to building this plugin. I'm looking to build my own custom actions and have a small issue. Here's a simplified version of the code in my action (extends RequestAction):

  override def sendRequest(requestName: String, session: Session): Validation[Unit] = {
    val start = clock.nowMillis
    if (requestName.toString().equals("abc")) {
      statsEngine.logResponse(session.scenario, session.groups, requestName.toString(), start, clock.nowMillis, OK, None, None)
      Success("success")
    } else {
      statsEngine.logResponse(session.scenario, session.groups, requestName.toString(), start, clock.nowMillis, KO, None, None)
      Failure("fail")
    }
  }

For some reason when this action is invoked from exec the test remains active if result is OK. Any suggestions? (Apologies in advance if this is not the right forum)
