Weird AfterInsert

I have two Domain class

class Reputation {
    int value
    static hasMany = [events: Event]
    static mapping = {
         value defaultValue: 0
  }
}

and 

class Event {
    int     point   
    static belongsTo = [reputation: reputation]
}

In ReputationService, I do something like this

reputation.addToEvents(new Event())
reputation.save() //which gonna make event and reputation save at once

But I want value in Reputation to be updated to : value is the sum of all events' point. So I add : 

Class Event {
    //....
    def afterInsert() {
    reputation.value += point
    reputation.save()
    } 
}

But it doesn't work: I always have a Reputation.value = 0.

What is wrong ? And how can I do this properly ?

If you look closely at the Grails documentation regarding Events and GORM you will notice it says:

Since events are triggered whilst Hibernate is flushing using persistence methods like save() and delete() won't result in objects being saved unless you run your operations with a new Session.

So, in your case it may be something like this:

Class Event {
    //....
    def afterInsert() {
      Event.withNewSession {
        reputation.value += point
        reputation.save()
      }
    } 
}
