ATG10.1 - Unable to confirm an order with Order Discount type promotion

Question

Hi,
I have created a promotion in ATG10.1. The promotion is an Order Discount type and i have configured a %off on the offer. Starting ATG10 we need to choose a template for configuring the promotion and then apply the rules and offer on it. I chose the Advanced condition and offer template and configured the rules and the offer.
Our requirement is to access the discountType property of the promotion applied on the order in a processor that gets executed in the processOrder pipeline. We have additional business logic in the processor depending on the discountType offered in the promotion. When we try to access the property we get an illegal argument exception. This is because the promotion that is being created is of super-type Order Discount whereas the discountType property is at the sub-type level.
We are accessing the property as below.
List<PricingAdjustment> pricingAdjustments = pOrder.getPriceInfo().getAdjustments();
for (PricingAdjustment pricingAdjustment : pricingAdjustments) {
RepositoryItem promotion = pricingAdjustment.getPricingModel();
String discountType = promotion.getPropertyValue("discountType");
Exception:
java.lang.IllegalArgumentException: Attempt to get a property value named discountType from item-descriptor type Order Discount
Any pointers or suggestions to fix this error would be helpful.
Thanks,
Srikanth

Yes, you are correct that discountType is defined at sub-type level. But if there is an entry in sub-type level, there is also an entry in the main "promotion" item-descriptor. PricingModel is nothing but main promotion repository item.
From the promotion ( pricingModel) repositoryItem, get the type ( type is a property defined at super level which says if this item is of type order discount, item dsicount or shipping discount. This type is not discountType ). Once you get the type value, call catalogRepository for that sub-type of promotion to get sub-type's repository item which contains the actual discountType.
From ATG 10 onwards, merchandising UI changed completely and sub types are not present. Templates are just for merchandising UI. But that should not effect your piece of code in the pipeline processors in processOrder pipeline chain. If you look at my above pseudo code, im getting the type, then querying catalog repository to get the sub-type repository item and then getting the discountType.
