Grails URL id field not getting mapped to params

Question

Here is my URLmappings.groovy

class UrlMappings {

static mappings = {
    "/$controller/$action?/$id?(.${format})?" {
        constraints {
            // apply constraints here
        }
    }
    "/ewhet/$id"(controller : "ewhet", action : "show")
    "/"(view: "/index")
    "500"(view: '/error')
    }
   }

Here is my ewhetController's show action:

class EwhetController {
    def index(){

    }
    def show(){
            def ctx = startAsync()
            ctx.start {
                render params
                //render "this invoked!!"
                ctx.complete()
            }
        }
}

Now when I enter the url as: http://localhost:8080/g24/ewhet/abc The abc does not get mapped to the params.id and when I render params, I get an empty map [:] . In case if url is entered as http://localhost:8080/g24/ewhet/show?id=abc the id field gets mapped to the params.id and I get:

['id':'abc']

So I just want to get the last part of the url mapped to the id parameter in params map without using any map in the url (like id=abc) as per Section 7.4.3 in Grails documentation So how is that possible and why is my approach not working?

Kindly note that I do not have any domain classes as I am using schemaless mongodb at my backend.

if you try to comment out the first mapping /$controller/$action?/$id?(.${format})?" ? — Fabiano Taioli, Jul 11 '13 at 12:47
If you change mappings to "/ewhet/$idx"(controller : "ewhet", action : "show") it's idx in params? — Fabiano Taioli, Jul 11 '13 at 12:51
@FabianoTaioli I have solved it.Actually restarting app with modified URLMappings did cause the config to run.The lesson is that the URLmappings.groovy was not getting compiled.U can give that as an answer to close it here. — rahulserver, Jul 11 '13 at 12:53

Try to reload the app after changing the UrlMappings.groovy to assure the new config is correctly loaded.

Infact I found a more general mapping which works for me.I added this code to the urlmappings:"/$controller/$id"(action:"show") – rahulserver Jul 11 '13 at 13:07
