Grails hasMany: when a child updates, changes to the parent version

Question

I use Grails and am pretty surprised at how relationships work hasMany. I have a typical relationship hasManywhere the parent id is in the child table. When I insert a child and try to save it through the parent, the version identifier of the parent is incremented. My question is: why change the parent version identifier when there is a change only in the child?

class Parent { 
    static hasMany = [children: child]
}

class child {
    string name 
    Parent parent
    static belongsTo = [Parent]
}

def p = Parent.get(1)
p.addToChildren(new Child(name: "Roy"))
p.save()

The version pincreases from 0 to 1. Is there a way to avoid this in Grails?

Due to a change in the identifier of the parent version, I get an outdated object exception. Any help?
