Grails - RESTful Web service responds with 404 when controller is defined - rest

Question

I defined a domain model class with a few properties and marked it as a RESTful resource using #Resource following the official Grails guide on Web services. Now, when testing the application (using Ruby's RestClient) I can see that things are working fine. However, after defining an associated Controller that overrides save method (for creating new resource), I've been getting 404 even on just simple GET requests. I defined some test objects using BootStrap so GET should be working.
My controller code looks like this:
class ModelController {
#Transactional
def save(Model model) {
def status = 201
if (model.validate()) {
model.save(flush: true, failOnError: true)
} else {
status = 422
}
render status:status
}
}
Do I still need to do something with the UrlMappings.groovy or is there something wrong with my controller code (all my unit tests for it are passing though)?
Update
I have created a sample project to demonstrate what's happening. Please check my bookstore-demo repository on GitHub. In the repository, I've defined 2 tags, rest-working, and rest-not-working. The first one marks the point where things are still working, and second one, as the name suggests, marks where I've created a controller that causes 404 response. This is pretty much what I've done with my actual project so far, and I'm getting the the same error.

The code looks OK, if you are getting a 404 then it sounds like its not even hitting this Controller. I would open developer console and try capture what URL it is hitting - URL being sent is potentially incorrect. If I am experimenting I tend to put println "1" println "2" and so on between my logics to see where the code is going or did it return it at all meaning it didn't even get there. so maybe if you doubt your code try this tactic between your if statements see which numbers get hit.
Also there is not a lot to go on to try give anything of more useful as feedback, but I would also check out the allowedMethods of this Controller if any defined...
unsure how it is being posted by if you have ..
static allowedMethods = [save: "POST", update: "POST", delete: "POST"]
try changing it to
static allowedMethods = [update: "POST", delete: "POST"]
unsure if this is still supported:
static allowedMethods = [save:['POST','GET'],update: "POST", delete: "POST"]
For all the methods refer to:
