</g:each>

Organization.controller

def confirmed(){
        def id = params.id
        println(id)

    }

Answer 1

Your gsp <g:link> looks good.

Please debug and check is ${training.id} have valid id.

<g:link controller="organization" action="confirmed" id="${training.id}">Apply</g:link>

still getting issue then temporary hard-code id to and check for Example:

<g:link controller="organization" action="confirmed" id="2">Apply</g:link>

Now in address bar you will URL like localhost:8080/organization/confirmed/2 and controller println also print the 2.

You can check documentation for more attributes and options
