global variables and "before" block

[script learner]

Hi All, 

I am trying to use a global variable to host a bunch of test parameters, but I don't see expected values.  For example (see [1] below), even if I set nbUsers to 5 in properties file, actual test results will show nbUsers is set to 2.  The logging messages inside "before" block do show that nbUsers is set to 5 though.  Can you please kindly point out what is the right way to do it?  I am using Gatling 3.5.1.

Thanks

Henry

class MyTestSimulation2 extends Simulation {
  val logger = org.slf4j.LoggerFactory.getLogger("TestLogger")
  val props = new Properties()

  before {
    val file = new File("/opt/gatling/conf/gatling.properties")
    if (file.exists()) {
      val fileReader = new FileReader("/opt/gatling/conf/gatling.properties")
       props.load(fileReader)
     }
    else {
       logger.error("/opt/gatling/conf/gatling.properties does NOT exist!");
     }
     logger.info("nbUsers: " + props.getProperty("nbUsers", "2"))
     logger.info("duration: " + props.getProperty("duration", "60"))
   }

....

  setUp(scnRunExec.inject(constantConcurrentUsers(props.getProperty("nbUsers", "2").toInt)
during(props.getProperty("duration", "60").toInt))).protocols(httpProtocol)

Don't put this code in the before block.

Thanks Stephane.  It works after I removing "before {" and "}".  So the before and after block are there for some presetup and tear down work with our own codes (no Gatling DSL) .
