Standard Add New button in Reference element in Table of items woks as "Create New and add it to the list". So if you add some referred item it is automatically attached to parent BO.
But what if I want just add item to the list but not create and attach it to the parent BO until I press Save Items?
Do I need in this case to duplicate this Reference element BO and make it Not persisted or there is a more simple way?
P.S. It is need for rule that now executes when new items is created, but it is needed that it executes when some set of items is added and then saved(created). It checks whether total amount of some value in them equals to another value and reports error.
