Grails + MongoDB GORM Plugin + One to Many == FAIL

I followed all of the rules… I did everything they told me to do… It even says that you can do this like normal GORM can…

A real simple structure:

package blah

class Author {
	String name
	static hasMany = [fiction:Book]
        static constraints = {
        }
}

package blah

class Book {
	String title
	static belongsTo = [ author: Author ]

    static constraints = {
    }
}

And from the example I tried…

import blah.*

def fictBook = new Book(title:"IT")
def nonFictBook = new Book(title:"On Writing: A Memoir of the Craft")
def a = new Author(name:"Stephen King").addToFiction(fictBook).save()

And I’m left with…

No signature of method: mongograilsquickstart.Author.addToFiction() is applicable for argument types: (mongograilsquickstart.Book)

This seems to just not work… Hit me up if you made this work, otherwise I’m gonna push a bug… dan@rhcedan.com
