Not sure if it is designed this way but it is wierd that the @Resource annotation doesn't work with generated scaffolding (generate-all). 

It is easy to have 2 controller serving 1 domain class, but not ideal. 

Evan's answer @ http://stackoverflow.com/questions/19465421/how-to-use-scaffolding-and-restfulness-together-in-grails-2-3 works. 

It's a bit more work but the only 1 controller is needed

Note: will need a entry point (linking to the same controller)
