When I run my grid on firefox, I can't see the rollbar, and when I use the arrow down or arrow up keys in keyboard he goes up and down in the roll instead of passing the itens. I would like to know what I'm doing wrong, because I've seen examples runing ok.
// define data formats
var str = new AW.Formats.String;
var num = new AW.Formats.Number;
obj.setCellFormat([str, str, str, num]);
// provide cells and headers text
// set number of rows/columns
