Grails one-to-many dynamic forms – train of thought

After searching around trying to find a good way to implement one-to-many dynamic forms in Grails, I have finally come across this post which does a very good job at explaining the details.

What I was basically looking for is a clean way to implement saving my domain objects in the backend, rather than the hacked way I did by hand picking request parameters and manually setting up my domain objects (I’m still fairly new to Grails), and the official docs fail to shed the light on the subtle details I found in this post, which is why I decided to post my own version of the one-to-many dynamic forms but with a little bit more complex domain objects to illustrate the use of enums which also I found is a bit of a gray area in the docs (or at least maybe for me).
