Recalculate Cart Prices Validator

Overview

The Recalculate Cart Prices Validator refreshes the prices on all line items in the cart based on the current product pricing and active promotions. This ensures that the cart reflects up-to-date prices, even if pricing has changed since the items were added.

This validator only runs on carts, not on confirmed orders.

Behavior

1. Skips validation entirely for confirmed Order entities (only runs on carts)
2. By default, recalculates at most once every 5 minutes per cart to avoid excessive processing. This interval check can be overridden with the ValidateAlways setting
3. For each line item:
   • Skips line items with a ManualDiscount property set to true
   • Resets the line item's discount amount
   • Enriches the line item with the current default price
   • Recalculates the line item's derived price fields
4. If any prices changed, marks the cart entity as updated
5. Always returns a successful validation (this validator updates data rather than blocking)
