Hi Tim,

The order details are retrieved in the HookParentRetrieved method.

       /// <summary>
        /// Parent Retrieved hook method
        /// </summary>
        /// <param name="bizObj">Parent business object</param>
        /// <param name="e">EventArgs</param>
        protected override void HookParentRetrieved(mmBusinessObject bizObj, mmBusinessStateChangeEventArgs e)
        {
            this.GetOrderDetail((int?)e.PrimaryKeyValue);
        }

I believe that HookParentRetrieved is called by the parent on any children when a new parent entity is retrieved.
