There is a HookPreSaveEntity method as well which I guess gets called before SaveEntity. I would create another method to do what you want in a preSave and then call that method from both HookPreSave and HookPreSaveEntity.

>>That seems about right. Make sure you also add to the child business objects the following in the HookConstructor method:

>>            this.AutoCancelOnParentCancel = true;
>>            this.AutoDeleteOnParentDeleted = true;
>>            this.AutoEmptyOnParentAdded = true;
>>            this.ForeignParentKeyField = "insert FK here";
>>		}
