How to automaticaly login and populate register form

I have seen somewhere that normally after the autorization is done the user is redirected to the register page but for me it seem to does not work however I have nothing special :D7 I have not touch to the user configuration and I have used Facebook preset for oauth connector so what I have omit

I have also installed netbeans to debug but with all the call of drupal function it's not easy ! I have seen a submodule in the forder of connector but I don't understand how it work action(Should I enable the trigger action module ?) and when the call occur ?
