Grails dynamic scaffolding error

I am new to Grails, I installed Grails 2.4 on Ubuntu 14.04

I have this Grails Domain:

class EndUser {

    String username
    String password
    String fullName

    String toString() {
        "$fullName"
    }

    static hasMany = [projects: Project, tasks: Task]

    static constraints = {
        fullName()
        username()
        password()
    }
}

and it's controller:

class EndUserController {

    static scaffold = true

    def index = {
//      redirect(action: "list")
    }
}

I am getting the error below, and everytime i create a new EndUser, I am getting an error page showing this message:

Error 500: Internal Server Error
URI
/ProjectTracker/endUser/create
Class
java.lang.NullPointerException
Message
null

What did I do wrong? and how can I fix it? Please let me know if I need to provide more info.

It looks like you hit this bug: https://jira.grails.org/browse/GRAILS-11430. It will be fixed in Grails 2.4.1; you can either wait until that version is released or try the workaround provided in the comments of that link, which has been reported to work.
