Domain classes used to reproduce the issue:
{code:title=User.groovy}
package blah
import org.bson.types.ObjectId
class User {
ObjectId id
String name
List
static embedded = ['addresses']
static hasMany = [addresses:Address]
static constraints = {
}
def beforeUpdate() {
this.name = name.toLowerCase()
}
}
{code}
{code:title=Address.groovy}
package blah
class Address {
String type
String identifier
static constraints = {
}
}
{code}
To reproduce the issue run this snippet twice in grails console
{code}
package blah
user = User.findByName("ratler")
if (!user) {
user = new User(name: "ratler")
}
address = new Address(address1:"Test")
user.addToAddresses(address)
user.save(flash: true)
{code}
