it works the same as vala except you dont need a break statement 

EG 

in vala :
        switch (eb.button) {
            case 1:
                do_something ();
                break;
            case 2:
                do_something ();
                break;
            case 3:
                do_something ();
                break;
        }

is same as Genie

        case eb.button
            when 1
                do_something ();
            when 2
                do_something ();
            when 3
                do_something ();



if you want to combine options just use comma

case eb.button
           when 1,2,3
                do_something ();

this is same as vala

     switch (eb.button) { 
            case 1:
            case 2:
            case 3:
                do_something ();
                break;
    }

please use latest vala master and send me code file if problem persists
