Error Scaffolding View Resolver - Grails

Today, while building a sample Grails application using the scaffolding approach, I encountered a new type of error, when running my Grails application. I had four domain classes and created a controller for each one of them. After the modelling of domain classes were complete, I added the following line of code inside my controller file to follow the scaffolding approach.

def scaffold = true

After this was done, when I executed the following command

grails run-app

I got the following exception on the screen;

After searching on this error in Google across multiple posts, I found that the cause of the error was the presence of the following additional line in each of my controller files

def index = { }

I removed this line from all the controller files and then retried running the demo grails application and it worked like a charm. If you have a similar ScaffoldingViewResolver issue for your Grails application, you can try this option out to see if it works for you.
