data not saving in after Update grails and stackoverflow error? - mongodb

Question

i m having a very weird issue, i m using grails afterUpdate in domain for saving the activity on db.
The code i m using to create a record in my collection "DatabaseEvent" is working in controller and saving the object perfectly but the same code is not saving object in afterUpdate() method ,
even the code is executing and not giving any error but still it is not saving the object
def afterUpdate () {
println "==++++==="
def dbEvent = new DatabaseEvent(type: "Created", entityClass : "Central Zone", objectId: this.id )
if(!dbEvent.save()){
println "======"
dbEvent.errors.each{
println it
}
}
else{
println "saved=="
}
}
it does print out "==++++===" and goes in else and print saved==
but the object is not saved in db, i m using mongodb
and sometimes it gives , the stackoverflow error and creates a lot of entries in just one call, i dont understand it, any solution for this ??
i have edited the question, as one i thing i noticed it is giving me stackoverflow when i use save(flush :true) and created a lots of records in one call and if i dont use it , it just dont create any ??

Transaction in service layer is coupled with the datasource associated, here you need to initiate a transaction to save the data like this
def afterUpdate () {
println "==++++==="
DatabaseEvent.withTransaction { status->
def dbEvent = new DatabaseEvent(type: "Created", entityClass : "Central Zone", objectId: this.id )
if(!dbEvent.save()){
println "======"
dbEvent.errors.each{
println it
}
}
else{
println "saved=="
}
}
}
