When it adds a CommerceItem to an order, the atg.commerce.order.purchase.CartModifierFormHandler sets the value of the item’s siteId property. The value is typically the site that was current when the item was added to the order. In some cases, though, it may be a different site; for example, if the CommerceItem is a cross-sell associated with a different site, this property will contain the site ID of the associated site.
Order items in the Order Repository have two properties for tracking the sites they are associated with:
creationSiteId– Contains the site ID of the firstCommerceItemadded to the order.siteId– If the order has not been submitted, this property contains the site ID of the lastCommerceItemadded to the order.CartModifierFormHandlerupdates this property each time aCommerceItemis added to the order or the quantity of an item is updated. When the order is submitted,CommitOrderFormHandlerorExpressCheckoutFormHandlersets this property to the site ID of the site from which the order was submitted.
The OrderLookup, ScheduledOrderLookup, and ApprovalRequiredDroplet servlet beans have siteIds and siteScope input parameters to determine which sites to look up orders for. (See Site Scope for information about these parameters.)
