Commerce Reference Store extends several core Commerce gift with purchase components.

StoreGiftWithPurchaseFormHandler

In Commerce Reference Store, the /atg/commerce/promotion/GiftWithPurchaseFormHandler component is of class atg.projects.store.promotion.StoreGiftWithPurchaseFormHandler. This class extends the core Commerce atg.commerce.promotion.GiftWithPurchaseFormHandler class to handle gift selection requests through AJAX. This allows the application to perform better when validation errors occur because the whole page does not need to be reloaded, only the error messages do. StoreGiftWithPurchaseFormHandler extends the handleMakeGiftSelection() method to redirect to different success and error URLs, depending on whether or not the request was made through AJAX. StoreGiftWithPurchaseFormHandler also extends the preMakeGiftSelection() method so that the application displays different error messages for each SKU attribute (color, size, wood finish).

StoreGWPManager

In Commerce Reference Store, the /atg/commerce/promotion/GWPManager component is of class atg.projects.store.promotion.StoreGWPManager. This class extends the core Commerce atg.commerce.promotion.GWPManager class. StoreGWPManager modifies the processAutoAdd() method in order to check the inventory level of an item before adding it as a gift to the order. Also, this class adds these helper methods:

StoreGiftWithPurchaseSelectionsDroplet

In Commerce Reference Store, the /atg/commerce/promotion/GiftWithPurchaseSelectionsDroplet component is of class atg.projects.store.droplet.StoreGiftWithPurchaseSelectionsDroplet. This class extends the core Commerce atg.commerce.promotion.GiftWithPurchaseSelectionsDroplet class by adding an additional quantityToBeSelected output parameter that represents the gift quantity in the order that has not been selected yet.
