one-to-many grails problem Grails hasMany: when child is updated, parent's version changes

I am using grailsGrails and i am quite surprised by the way has manyhasMany relationships work. I have a typical has manyhasMany relationship where the parent id is in the child table. When iI insert a child and try to save it through the parent object..The, the parent objectsobject's version id gets incremented. My question is why: Why should the parent's version id change when there is a change only in the child object.?

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()

theThe version of pp gets incremented from 0 to 1. Is there any way iI can avoid this in grailsGrails? Due

Due to the change in version ID of the parent iI get a stale object exception. Any help?
