AddCustomerToOrder now publishes OrderEvent internally, ensuring all callers (admin, shop, draft order, and login-merge) trigger the event. Fixes vendurehq#5189.

📝 WalkthroughWalkthrough
Suggested reviewers: Merge Risk: 🟡 Moderate · up to Merge cleanup failures may be ignored while customer and coupon changes are committed and an order update event is published, allowing downstream processing of a partially merged order. Relation-valued custom fields can also fail to match consistently when equivalent IDs are returned in different orders; these issues should be fixed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

Full details: Linked Issues checkExplanation The context confirms centralized customer-assignment events and routing merge assignments through addCustomerToOrder. It does not clearly confirm an explicit deleted OrderEvent for the guest order required by issue Full details: Out of Scope Changes checkExplanation The PR adds coupon revalidation and relation-valued OrderLine custom-field hydration.

Thanks for this. The core idea is right: making addCustomerToOrder the single place that publishes the event, and deleting the duplicate publish in updateOrderCustomer, is a better design than four call sites each remembering to publish. Two things need fixing before it can merge.
1. The merge path now publishes a spurious event on every login
mergeOrders runs on every createNewAuthenticatedSession, not only when a guest cart exists (session.service.ts:120). With no guest order, OrderMerger.merge falls through to the final branch and returns { order: existingOrder } (order-merger.ts:51-55). There is then nothing to delete, insert, modify or remove, so execution goes straight to:
order = await this.addCustomerToOrder(txCtx, order, customer);The order already belongs to that customer. Nothing changes, but an OrderEvent(ctx, order, 'updated', customer) is now published.
The problem is not the volume, it is that the event is untrue. OrderEvent's input is typed Customer | ModifyOrderInput | { customFields: any } (order-event.ts:7), so passing a Customer is precisely the signal subscribers use to detect "a customer was just assigned to this order". Here, none was. Note also that this login path currently publishes zero OrderEvents, so this is a new event where there was none, not one more among many.
updateOrderCustomer already guards this at line 557:
if (currentCustomer?.id === customerId) {
// No change in customer, so just return the order as-is
return order;
}Now that addCustomerToOrder owns the publish, it needs to own that guard too:
if (idsAreEqual(order.customer?.id, customer.id)) {
return order;
}One caveat on the relation load: getOrderOrThrow's default relations do include customer, but the Order-instance overload of addCustomerToOrder takes whatever the caller passes, so order.customer may be undefined simply because it was never hydrated. Compare against the customerId FK rather than letting "not loaded" read as "changed".
2. Decide on the coupon revalidation
Your own description has a "Breaking changes" section noting that guest coupon codes are now silently stripped during merge, and concluding it is "a behavioral change beyond the scope of 'fire an OrderEvent'". I agree with that assessment, so it should not ship as an unremarked side effect. Either drop it or commit to it with a test and a changeset entry.
There is a smaller robustness point behind it. The old code was order.customer = customer followed by save(order, { reload: false }), which is about as close to unthrowable as a write gets. The new path can reach removeCouponCode, which calls applyPriceAdjustments, and a custom PromotionCondition or PromotionAction can throw from there. That lands in the catch at line 2276, which rolls the merge transaction back and returns existingOrder. Nothing is destroyed, but if existingOrder was empty or undefined the customer signs in to an empty cart while their guest order sits orphaned in the database, with only a server log to explain it. Narrow, but it is a failure mode the previous code did not have.
Happily, the guard in point 1 fixes both: returning early when the customer is unchanged skips the coupon loop entirely on the login path.
3. Tests
The test checkbox is unticked on a PR whose entire observable output is an event, and the linked issue includes a reproduction. packages/core/e2e/shop-order.e2e-spec.ts and packages/core/e2e/customer.e2e-spec.ts already cover these mutations. Please assert exact counts rather than "at least one", since the count is the whole point of removing the duplicate publish:
setCustomerForOrderpublishes exactly oneOrderEventwithtype: 'updated'and the correct customer.updateOrderCustomerstill publishes exactly one, not zero and not two. This is the regression the PR is most likely to introduce.- Logging in with an existing active cart and no guest cart publishes zero
OrderEvents. This one fails against the current diff.
4. Docs
addCustomerToOrder is a public, documented service method whose doc comment is still the one line "Associates a Customer with the Order." It now publishes an event that plugin authors are expected to subscribe to. Please say so, with an @since for the release this lands in, matching how updateOrderCustomer documents @since 2.2.0.

closes #5189.
Description
addCustomerToOrdernow publishesOrderEvent(ctx, order, 'updated', customer)internally. This ensures all code paths — admin (updateOrderCustomer), shop (setCustomerForOrder), draft order (setCustomerForDraftOrder), and login-merge — emit the event when a customer is associated with an order.The duplicate event publish in
updateOrderCustomerwas removed. The rawsave()inmergeOrderswas replaced with a call toaddCustomerToOrder, which also gains coupon code revalidation.Note
Breaking changes
The new code delegates to addCustomerToOrder, which also validates coupon codes (lines 2049-2059) and removes any that are invalid for the newly assigned customer. This means if a guest had coupon codes that don't apply to their registered account, they'll be silently stripped during merge.
This is arguably the correct behavior — but it's a behavioral change beyond the scope of "fire an OrderEvent."
