Fetch Quantity on Product Configurator Cfg_InstInitialize event

Hi,

I am trying to define a logic based on the Quantity of a Product.

a) Would like to get the Quantity on Cfg_InstInitialize event. I tried to use GetObjQuantity method, but it looks like it is not fetching the values.

followup question: if there are 2 tabs in the Product configurator and by default Product configurator launches on Tab1. Will we be able to fetch the Quantity of a Product from Tab2?

b) I tried the same on 'Cfg_ChildItemChanged' event by using OldQty and NewQty inputs. It seem to work, but when I keep increasing the count on the Quantity, the Old and New values don't seem to bring the expected values.
