Grails 3.2.2 spring-security-ui override RegisterController not working

Question

I am working on a Grails 3.2.2 Plugin in which I am trying to override the RegisterController from spring-security-ui as well as the register.gsp. I have used the s2ui-override command which has created me the required controller and at the moment I only added a println to see it working, but it seems to be still going to the original one. So far I have:

RegisterController

import org.springframework.security.core.userdetails.UserDetailsService
import org.springframework.security.core.userdetails.UserDetails
import grails.plugin.springsecurity.ui.RegisterCommand

class RegisterController extends grails.plugin.springsecurity.ui.RegisterController {

static defaultAction = 'register'

UserDetailsService userDetailsService

@Override
def register(RegisterCommand registerCommand) {
    println "IN MY CONTROLLER!!"
    def registerReturn = super.register(registerCommand)
    if (registerReturn?.emailSent) {
        UserDetails createdUser = userDetailsService.loadUserByUsername(registerCommand.username)

        println "New user ${createdUser}"
    }
    registerReturn
}

def otherAction() {
    println "IN MY CONTROLLER!!"
    println "userDetailsService = ${userDetailsService}"
    "Hellloooo"
}

}

register.gsp same as the original, only added

<p style="color:red;"> HELLLOOOOOOO </p>

immediately after the body tag

UrlMappings

class UrlMappings {

static mappings = {
    "/$controller/$action?/$id?(.$format)?"{
        constraints {
            // apply constraints here
        }
    }

    "/"(view:"/index")
    "500"(view:'/error')
    "404"(view:'/notFound')
 }
}

Result when running the app: I can see my sample red text at the top, but cannot see the output in the console, although I am getting a warning when running the app. Console output when going to the "register" URL:

 Running application...
 WARNING: The [register] action accepts a parameter of type [grails.plugin.springsecurity.ui.RegisterCommand] which does not implement grails.validation.Validateable.  Data binding will still be applied to this command object but the instance will not be validateable.

   @Override

Though when going to "register/otherAction" I am getting:

IN MY CONTROLLER
userDetailsService = grails.plugin.springsecurity.userdetails.GormUserDetailsService@10ed50b0

Interestingly, if I publish the plugin locally (my .m2 dir) and import it into an app, I am getting my printlns in the console, BUT my gsp is now not being used (I cannot see my red Hello text). Console output:

IN MY CONTROLLER!!
// unimportant mailing error
New user grails.plugin.springsecurity.userdetails.GrailsUser@364492: Username: test; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: false; Granted Authorities: ROLE_NO_ROLES

Anyone can help on where am I going wrong? I am happy to provide any other resources which may help.

So I have a fix (maybe a workaround):

RegisterController

class RegisterController extends grails.plugin.springsecurity.ui.RegisterController {

static namespace = 'my-great-plugin'

UserDetailsService userDetailsService

@Override
def register(RegisterCommand registerCommand) {
    println "IN MY CONTROLLER!!"
    def registerReturn = super.register(registerCommand)
    println "Got return from super call ${registerReturn}"
    if (registerReturn?.emailSent) {
        UserDetails createdUser = userDetailsService.loadUserByUsername(registerCommand.username)
        println "New user ${createdUser}"
    }
    registerReturn
}

def otherAction() {
    println "IN MY CONTROLLER"
    println "userDetailsService = ${userDetailsService}"
    "Hellloooo"
}

MyPluginUrlMappings.groovy

static mappings = {
    "/register/$action?/$id?(.$format)?" { 
        controller = 'register' 
        namespace = 'my-great-plugin' 
    }
}

MyPluginGrailsPlugn.groovy

 def loadAfter = ['springSecurityCore', 'springSecurityUi', 'springSecurityRest']

And it works now!

I am still open to suggestions on how to handle this better
