Problems with Scaffolding in Chapter 3

[nooruddin]

Hi,

I was exploring grails with this amazing book. While progressing through chapter : 3 I came across Scaffolding. I added "def scaffold = true" in both Race and Registration controller. But when I ran my application, clicking on controllers showed me error that index.gsp doesn't exist in grails templates. I changed the closure name to list and tried clicking on RaceController again and came across the following error which is preventing me from progressing ahead. Error dumped below :
