Summary

Fixes #5426.

When a Safe's ComposableCoW fallback handler is removed or reset (e.g. via the Safe TX builder), open TWAP orders can no longer be picked up by the watchtower, so they will never execute. The orders table kept showing them as Pending, giving no signal that the order is effectively dead.

The module already verifies the fallback handler (useIsFallbackHandlerRequired) but only used it in the order-creation form — never in the orders table. This threads that signal into the status build so open orders are surfaced with the existing Unfillable badge.

Changes

  • TwapOrdersUpdater reads useIsFallbackHandlerRequired() and passes it into buildTwapOrdersItems.
  • buildTwapOrdersItems marks an item isUnfillable only when the handler is broken and the order is still open (Pending).
  • The parent/part store-order mappers forward isUnfillable so the table renders the badge; still-open parts of an affected order are flagged too.

No new status enum — reuses the existing order.isUnfillable badge path, so final states (Fulfilled/Cancelled/Expired) are untouched.

Testing steps

  1. Connect a Safe wallet, place a TWAP order.
  2. Reset/replace the Safe's fallback handler (Safe TX builder).
  3. Wait for the handler verification to refresh (~10 min) and reload the TWAP page.
  4. The open order (and its open parts) now shows Unfillable instead of Pending.

Summary by CodeRabbit

  • New Features

    • TWAP orders now display an “Update fallback handler” warning (with a dedicated tooltip) when open TWAP orders can’t be created due to a broken/reset Safe fallback handler.
    • Status and estimate components now prioritize this fallback-handler unfillable messaging for pending/scheduled TWAP orders.
  • Bug Fixes

    • Unfillable state is now propagated consistently across TWAP mapping, part orders, and orders table rendering—without conflicting writes for composable orders.
    • Warning text/tooltips are now aligned between order rows and TWAP status displays.
  • Tests

    • Added coverage for the fallback-handler warning UI in TWAP status and estimated execution price components.

… is reset

When a Safe's ComposableCoW fallback handler is removed or reset, open TWAP
orders can no longer be executed by the watchtower, but the orders table still
showed them as pending. Thread the existing fallback-handler verification into
the order status build so open orders (and their still-open parts) surface the
existing Unfillable badge.

Review Change Stack

Walkthrough

This PR marks TWAP orders and parts as unfillable when a Safe fallback handler is broken or reset. It threads the new flag through TWAP item creation, store mapping, table-state computation, and order-status rendering, with updated tests and locale source references.

Changes

TWAP unfillable status

Layer / File(s) Summary
Type and item construction
apps/cowswap-frontend/src/modules/twap/types.ts, apps/cowswap-frontend/src/modules/twap/updaters/TwapOrdersUpdater.tsx, apps/cowswap-frontend/src/modules/twap/utils/buildTwapOrdersItems.ts
Adds optional isUnfillable to TwapOrderItem, derives fallback-handler state in the updater, and passes it into TWAP item building to mark pending orders unfillable.
Store order propagation
apps/cowswap-frontend/src/entities/twap/services/mapTwapOrderToStoreOrder.ts, apps/cowswap-frontend/src/modules/twap/utils/mapPartOrderToStoreOrder.ts
Maps isUnfillable onto store Order objects and mirrors parent unfillable state onto open parts when pending or scheduled.
Orders table unfillable state
apps/cowswap-frontend/src/modules/ordersTable/hooks/useOrdersTableList.ts
Keeps composable orders’ derived unfillable state separate from the generic pending-order persistence path.

Hoppity-hop, the handler flipped,
So TWAP orders got a warning strip.
Unfillable now glows right in view,
With tooltip notes of what to do. 🐇

Naming drifts across layers: isFallbackHandlerRequiredisFallbackHandlerBroken.

The hook is useIsFallbackHandlerRequired, but the value is renamed to isFallbackHandlerBroken when threaded through here. The semantics line up (both represent "handler is not in the correct/verified state"), but the rename could confuse future readers tracing the flag across TwapOrdersUpdater.tsxbuildTwapOrdersItems.ts. Consider keeping a consistent name (e.g., isFallbackHandlerBroken end-to-end, or documenting the rename) for easier traceability.

Hey @tenderdeve , thank you for the attempt to fix this issue.

Before I report my feedback here, I'd like to clarify whether you verify yourself the results of AI-fixes you create? It would be awesome if you could have verified everything before sending a final outcome to our review. Thank you for understanding.

As for the PR:

  1. Order status and scheduled parts indeed are labeled as 'unfillable'
  2. however, the order itself is not displayed in the Unfillable tab in the table
Image
  1. 'Fills at' still shows 'pending execution', however. should not. It would be great to show why the order is unfillable.
Image

Addresses @elena-zh's review feedback:
- Categorize composable (TWAP) orders into the Unfillable tab by respecting their
  derived isUnfillable flag in useOrdersTableList, instead of recomputing it purely
  from balance/allowance (which also overwrote the flag). Regular orders keep their
  existing balance-based behaviour.
- Show an 'Unfillable' indicator with an explanatory tooltip in the 'Fills at'
  column for affected TWAP orders instead of 'pending execution'.
- Rename the threaded flag to isFallbackHandlerBroken for consistency across layers.

@elena-zh thanks for the detailed review — and fair point on verification; I've verified this locally now (Unfillable tab + Fills-at + badge on an emulated handler-reset TWAP) and confirmed typecheck/lint pass.

Pushed 4b3f47f addressing all three:

  1. Unfillable tab — the order didn't appear because useOrdersTableList recomputed isUnfillable purely from balance/allowance and even overwrote the flag. It now respects the derived flag for composable (TWAP) orders, so the order lands in the Unfillable tab. Regular orders keep their existing balance-based behaviour.
  2. 'Fills at' — no longer shows 'pending execution' for these orders; it now shows an Unfillable indicator with a tooltip explaining why (fallback handler reset), instead of the pending price row.
  3. Renamed the threaded flag to isFallbackHandlerBroken for consistency (also flagged by coderabbit).

TWAP parents no longer persist isUnfillable

OrderStatusBox and other ParsedOrder consumers still read order.isUnfillable, so skipping setIsOrderUnfillable for all composable orders means a TWAP parent can stop reflecting genuine balance/allowance-based unfillable state in the store. The table still uses the recomputed flag locally, but the persisted parent order stays stale.

Hey, now the changes look better, but all my comments are not addressed.

  1. As I mentioned above, parts should not be in 'pending execution' state. It should show the same info as for the parent order
Image
  1. Parent order status should have the same design for 'unfillable' label: it should contain the warning icon saying what is wrong there (see the content in p.4)
Image Image
  1. Parent order Fills at column should show a reason instead if 'Unfillable'. Compart it with the order below on the screenshot. It would be great to show 'Update fallback handler' there.
Image
  1. Hovering a mouse on the reason should show a bit more explanation. The design should be same
Image
  • 'Update fallback handler' - title
  • 'Your Safe fallback handler was changed after TWAP orders were placed. All open TWAP orders are not getting created because of that. Please, update the fallback handler in order to make the orders work again." description.
  1. Please, make sure that all new messages were ready for translations

…ck handler

Reuse the existing balance/allowance unfillable design for open TWAP orders
blocked by a reset Safe ComposableCoW fallback handler:

- Fills-at column now shows an "Update fallback handler" reason (via the shared
  OrderEstimatedExecutionPrice label) instead of "Pending execution"/"Unfillable",
  for the parent order and its still-open parts.
- Status badge shows the danger warning icon with a tooltip explaining the reset
  fallback handler (FallbackHandlerWarningTooltip), matching the other warnings.
- Thread the fallback-handler reason through OrderRow so parent and parts render
  the same reason and tooltip.

Copy matches the existing SetupFallbackHandlerWarning strings, so no new catalog
entries are added. Adds unit tests for the reason label and tooltip content.

@elena-zh @fairlighteth updated in e44a66c — reworked the whole failed/unfillable presentation to match the existing balance/allowance design (per your comments 1-5):

  1. Parts no longer show "pending execution" — every still-open part now shows the same unfillable reason and tooltip as the parent.
  2. Status badge now carries the danger warning icon + tooltip (new FallbackHandlerWarningTooltip), same design as the balance/allowance warnings.
  3. Fills-at column shows the reason "Update fallback handler" instead of "Unfillable" (reuses the shared OrderEstimatedExecutionPrice label).
  4. Hover shows the title + explanation. I used the exact copy from your Captcha shows a success state when JWT token is failed #7801 note — which turned out to already exist in the catalog (from SetupFallbackHandlerWarning), so no new translation strings are added.
  5. All strings go through the lingui macros and extract cleanly.

Added unit tests covering the reason label and the tooltip content so this design can't silently regress. Typecheck/lint/i18n-extract all pass locally.

Note: the end-to-end path (real Safe + resetting the ComposableCoW fallback handler + ~10-min watchtower refresh) I can't reproduce locally, so the manual verification is on the emulated flag path plus the added unit tests — flagging that explicitly.

Address the self-flagged TODO for the missing return type.

The author left a TODO/eslint-disable for the missing explicit return type on FallbackHandlerWarningTooltip. Since it returns JSX, an explicit JSX.Element (or React.JSX.Element, depending on how this repo's React 19 types are set up) return type would let you drop the disable comment.

Duplicate fallback-handler warning copy/markup.

The "Update fallback handler" heading and the full explanatory paragraph ("Your Safe fallback handler was changed after TWAP orders were placed...") are duplicated verbatim here and in FallbackHandlerWarningTooltip (WarningTooltip.pure.tsx, lines 149-168). Any future copy edit (or the pending i18n rework mentioned in the PR follow-ups) requires updating both places in sync. Consider extracting a shared FallbackHandlerWarningContent component/text used by both call sites.

Also worth a look while touching this block: internationalizedWarningText is now a 4-branch nested ternary; a small lookup keyed by the flag constants would read more clearly than the current if/else chain.

@tenderdeve , thanks, but case 2 from my previous comment #7802 (review) is still not addressed.

The parent TWAP status badge only reflected child balance/allowance warnings,
so an order blocked by a reset Safe ComposableCoW fallback handler still showed
a plain status with no reason. Derive the fallback-handler-unfillable state from
the parent or any still-open part and render the same danger design and
FallbackHandlerWarningTooltip already used on the parts and Fills-at column.

Also move UPDATE_FALLBACK_HANDLER_WARNING into a dedicated constants module so
the component file no longer exports a non-component value.

@elena-zh addressed case 2 in 6db4785 — the parent TWAP status badge now shows the same danger design + fallback-handler tooltip as the parts. The parent badge previously only reacted to child balance/allowance warnings, so a fallback-handler-blocked order rendered a plain status; it now derives the unfillable state from the parent or any still-open part. Also moved UPDATE_FALLBACK_HANDLER_WARNING into a constants module per the review nit.

Duplicate fallback-handler-unfillable predicate.

isFallbackHandlerUnfillable here is byte-for-byte identical to the one defined in OrderRow.container.tsx. Extract this into a shared utility (e.g. an ordersTable/twap utils module) and import it in both places to avoid drift if the predicate logic changes.

♻️ Suggested extraction
// e.g. apps/cowswap-frontend/src/modules/ordersTable/utils/isFallbackHandlerUnfillable.ts
import { ParsedOrder } from '...'
import { OrderStatus } from '...'

export function isFallbackHandlerUnfillable(order: ParsedOrder): boolean {
  return order.isUnfillable === true && (order.status === OrderStatus.PENDING || order.status === OrderStatus.SCHEDULED)
}
-  const isFallbackHandlerUnfillable = (order: ParsedOrder): boolean =>
-    order.isUnfillable === true && (order.status === OrderStatus.PENDING || order.status === OrderStatus.SCHEDULED)
+  // imported from shared utils

⚠️ AI Review (Codex GPT-5, worked 2m): cover the parent fallback-handler badge branch

Finding: [NON-BLOCKING] Cover the parent fallback-handler badge branch

  • Location: apps/cowswap-frontend/src/modules/ordersTable/pure/TwapStatusAndToggle/TwapStatusAndToggle.pure.tsx:62
  • The latest fix adds the parent TWAP status-badge path for fallback-handler-blocked orders, but the added tests only cover the Fills-at label/tooltip path.
  • Since this branch addressed the latest parent-badge review feedback, please add a focused test that a pending or scheduled parent with isUnfillable: true renders the fallback-handler warning on the parent status badge.

Suggested fix

  • Add a TwapStatusAndToggle test for a fallback-handler-blocked parent.
Review scope and related context

This is separate from the existing CodeRabbit thread on the duplicated isFallbackHandlerUnfillable predicate. That thread is about deduping the helper; this comment is only about preserving the newly added parent status-badge behavior with a focused test.

🤖 Prompt for AI agents
Verify this finding against current code. Fix only if still valid, keep the change minimal, and validate with the targeted test.

Context:
- apps/cowswap-frontend/src/modules/ordersTable/pure/TwapStatusAndToggle/TwapStatusAndToggle.pure.tsx:62
- The PR added fallback-handler warning rendering for the parent TWAP status badge after review feedback.
- Existing new tests cover OrderEstimatedExecutionPrice and TwapOrderStatus, but not TwapStatusAndToggle.
- Add a focused test that renders a pending or scheduled parent with fallback-handler isUnfillable and asserts the parent status badge exposes the fallback-handler warning.
