hi again, i used the convenient way of grouping requests in gatling 1 and would like to do something like that now.
but when i do something like
val scn = scenario("Some scenario")
group("group 1") {
exec(http("Open page")
.get("/page")
.headers(headers_73))
.pause(0, 7)
}
.group("other page") {
exec(http("Open other page")
.get("/promotions")
.headers(headers_73)
)
}
the result is

That's just a race condition with the timer asking to display the console info one last time just after it was asked for shutdown.
Just ignore it, we'll clean this up in the next release.
Thanks for reporting.

thank you for fast reply
but i expect the scenarios to actually send requests ) and they dont do that if i try to use groups
here is an example scenario
package wpl20
import io.gatling.http.Predef._
import io.gatling.core.scenario.Simulation
import io.gatling.core.Predef._
import scala.concurrent.duration._
import bootstrap._
import assertions._
class TestScenario extends Simulation {
val httpConf = http
.baseURL("http://edition.cnn.com")
.acceptHeader("text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
.acceptEncodingHeader("gzip, deflate")
.acceptLanguageHeader("en-US,en;q=0.5")
.connection("keep-alive")
.userAgentHeader("Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36")
.disableFollowRedirect
val scn = scenario("Navigation")
group("Home page") {
exec(http("Open home page")
.get("/")
.headers(headers_73))
.pause(0, 7)
}
group("world page") {
exec(http("Open world page")
.get("/WORLD/")
.headers(headers_73)
)
}
setUp(scn.inject(ramp(2 users) over (30 seconds))).protocols(httpConf)

There's dots missing in front of your group method calls (just like in Gatling 1).
val scn = scenario("Navigation")
.group("Home page") {
exec(http("Open home page")
.get("/")
.headers(headers_73))
.pause(0, 7)
}
.group("world page") {
exec(http("Open world page")
.get("/WORLD/")
.headers(headers_73)
)
}
