why zkui generators still use closures in grails controller rather than methods?

[mauro]

I've created a grails application for test.

Create a domain class the run zkui-generate-all.

In the grail controller I have:

def index = {

        redirect(action: "list", params: params)

    }

    def list = {}

    def create=  {

        def bookInstance = new Book()

        bookInstance.properties = params

        return [bookInstance: bookInstance]

    }

    def edit = {

        def bookInstance = Book.get(params.id)

        if (!bookInstance) {

            flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'book.label', default: 'Book'), params.id])}"

            redirect(action: "list")

        }

        else {

            return [bookInstance: bookInstance]

        }

    }

Why still using closures rather than methods?

I've modified, for example the create closure to:

def create() {

        respond new Book(params)

    }

using the new respond method and it works.
