Description
I could not get this error to occur in a test unfortunately, but occurs just fine in a controller. See the 3 domain classes below. The problem seems to be with changing the child in the beforeUpdate of the Parent. The error complains that the subChilds (children of Child) were not processed by the flush.
class Parent {
static hasMany = [ childs : Child ]
def beforeUpdate =
{
calc()
}
def calc =
{
this.childs.each {it.s = "change"}
}
}
class Child {
static belongsTo = [Parent];
static hasMany = [ subChilds : SubChild ]
String s
}
class SubChild {
static belongsTo = [Child];
String s
}
class WooController {
def index = {
Parent p = Parent.get(1)
p.addToChilds(new Child(s:"testy"))
Parent.withTransaction
{
p.save(flush:true)
}
render "${p} -> ${p.childs}"
}
}
class BootStrap {
def init = { servletContext ->
Parent p1 = new Parent().save(flush:true)
p1.save(flush:true)
}
def destroy = {}
}
Run the app. Now the first time you go to
http://localhost:8080/<appname>/woo
Parent : 1 -> [Child : 1]
As expected. But if you refresh the page again you get the error:

but how is it possible, that everything works fine with 1.1? The error only occurs with 1.1.1 here, and the hibernate bugreport is from 2007. Something must have changed between 1.1 and 1.1.1, the hibernate codebase should be the same in both versions 
.
. 
I've created a "similiar" issue about delete() methods not being called from beforeDelete events. I don't have a clue if these are related but thought they have some similarities since they both involve beforeXXXX.
