Grails - are cascades transactional

In Grails, do cascades happen within a transaction?

Heres an example from the Grails documentation to demonstrate:

Given the following classes:

class Airport {
    String name
    static hasMany = [flights: Flight]
}

class Flight {
    String number
    static belongsTo = [airport: Airport]
}

If I now create an Airport and add some Flights to it I can save the Airport and have the updates cascaded down to each flight, hence saving the whole object graph:

new Airport(name: "Gatwick")
        .addToFlights(new Flight(number: "BA3430"))
        .addToFlights(new Flight(number: "EZ0938"))
        .save()

Does Grails/Hibernate guarantee this operation to be atomic, even if the code is not wrapped in any transaction?

No, without using transactions there is no guarantee of atomic operations such as that through GORM or Hibernate.
