How do Grails Controller action arguments work when the arg is a Domain class instance?
Hi Grails Community,
It's been several years since my last post in here. Does anyone have insight into how Domain objects as Controller action arguments are data-bound? I posted this on SO too, with a little more detail: https://stackoverflow.com/questions/46532091/grails-3-3-1-controller-action-with-domain-object-argument-how-is-data-bound
Any help would be great. Eventually I would like to implement a editIfExistsElseCreate type action, so knowing how this works would be ideal.
