fix(ui)!: consolidate all form request types into a single queue - #19203
Three kinds of requests talk to the server while you edit a document:
Form-state refresh — you typed, so the server recalculates things like conditional field visibility, row labels, computed values, and new server components
Autosave — periodic background draft saves
Explicit save — you clicked Save or Publish (or cmd + s)
Before this PR, these ran on separate tracks and could overlap, so responses could land out of order and a save could start before an earlier server update had merged in. This PR puts all three into one track, so that it can effectively manage traffic across all three types of requests. So now:
Only one request runs at a time
Only one request can be pending while the running request executes
The pending slot is ranked: explicit save > autosave > form-state refresh. If something more important shows up, whatever was waiting gets thrown away
Breaking Changes
The useQueue hook existed prior to this PR, but it's now instantiated once for all request types within the form.
Custom components that call queueTask directly need to pass the task as an option. Task errors are no longer caught and logged by the queue; they reject the returned promise, so handle them at the call site:
The queueTask method now accepts a priority and returns either a completed result or a superseded status:
const{ queueTask }=useQueue()constloadPosts=async()=>{constresult=awaitqueueTask({priority: 0,// Lower numbers take precedencetask: async()=>{constresponse=awaitfetch('/api/posts')returnresponse.json()},})if(result.status==='completed'){returnresult.value}}
This hook is also now marked as internal.

#13416 moved autosave execution through the same submit flow as regular submits, so that server hook changes are reflected in form state. But form-state refreshes still ran through a separate queue, allowing responses to merge out of order or saves to start before an earlier form-state response had merged.

Walkthrough
The pull request revises useQueue and integrates prioritized, currentness-guarded work into form-state refreshes and submissions. Autosave now submits directly. Unit and end-to-end tests cover queue behavior and form request ordering.
Changes: Form request queue and autosave
Layer / File(s)
Summary
Queue contract and task execution packages/ui/src/hooks/useQueue.ts, packages/ui/src/hooks/useQueue.spec.ts, packages/ui/src/exports/client/index.ts, packages/ui/src/fields/Relationship/Input.tsx, docs/migration-guide/v4.mdx
useQueue now retains at most one pending task by priority, returns completed or superseded results, and rejects task errors. Reset invalidates active task context and supersedes pending work. Callers, exported types, tests, and migration guidance reflect the revised API.
Form-state refresh and reset handling packages/ui/src/forms/Form/useFormState.ts, packages/ui/src/forms/Form/index.tsx
Form-state refreshes are queued and guarded against stale results. Form reset, initialization, replacement, and unmount reset queued work. Validation applies results only when its task remains current.
Prioritized form submissions packages/ui/src/forms/Form/requestPriority.ts, packages/ui/src/forms/Form/types.ts, packages/ui/src/forms/Form/useFormSubmission.tsx, packages/ui/src/forms/Form/index.tsx
Submission type determines queue priority. Submission processing checks task currentness around validation and response handling, refreshes form state for relevant outcomes, and restores request state.
Autosave submission and status packages/ui/src/elements/Autosave/index.tsx
Autosave submits directly. It tracks outstanding requests and saving-indicator timing, handles submission errors, and retries when validity settles after an invalid attempt.
Form request queue coverage test/form-state/collections/*, test/form-state/config.ts, test/form-state/payload-types.ts, test/form-state/e2e.spec.ts, test/versions/e2e.spec.ts
The form-state E2E suite adds coverage for autosave, refresh, save, and publish ordering. Test fixtures add conditional autosave fields and a draft-enabled collection. Version tests wait for successful autosave responses.

payloadcms/payload#19368: The PR changes autosave and form-state response ordering, but the issue’s server-computed state cases are not clearly covered.
payloadcms/payload#19363: The PR gives explicit submissions higher priority than autosaves and tests save/publish ordering.
payloadcms/payload#18425: The PR queues form-state refreshes and guards against stale results, which aligns with the reported late-response behavior.

Merge Risk: Low · previous review a6520
The change consolidates form-state refresh, autosave and explicit save into one prioritized queue. The migration guide example should show rejection handling before merge, because anyone copying it can get an unhandled promise rejection. No blocking runtime risk has been established.

Explanation
The title "fix(ui)!: consolidate all form request types into a single queue" matches the main change. The changeset moves form-state refreshes, autosaves, and explicit saves onto one queue, as the summaries and the PR description both state. The title omits the breaking change to the internal useQueue API and the priority ranking, which is acceptable because the title need not cover every detail.
Full details: Description check
Explanation
The description explains the three request types (form-state refresh, autosave, explicit save). It describes the single-queue design, the priority ranking, and the breaking changes to the useQueue API with migration examples. It also links related issues and PRs. It matches the changeset closely.
Full details: Linked Issues check
Explanation
The PR addresses [#18348]. Autosave now submits through the shared form submission queue instead of a separate autosave queue. The queue runs one task at a time, and autosave processing state is enabled when each autosave task starts. The submission code preserves edits made during background processing. The form-state E2E suite adds coverage for edits during queued autosaves and autosave failures.
Full details: Out of Scope Changes check
Explanation
The changes remain within the stated shared form-request queue scope. The queue API, form-state refresh integration, autosave and submit integration, migration documentation, component call-site updates, and unit and E2E tests support the consolidation described in the PR. The test collection and version-test updates support the new autosave behavior. No unrelated change is demonstrated.

Explicit saves now disable the form when they are scheduled instead of
when they reach the front of the queue, matching main. The submit guard
then rejects any submission made while a save waits, so a draft cannot
be saved while a publish is queued.
Each submission only releases what it took. An autosave no longer clears
the disabled or processing state held by a queued save, and an explicit
save holds the disable until its task settles rather than releasing it
when the response arrives.
Replaces the useFormSubmission unit tests with e2e coverage in the
shared form request queue suite.
Keep scheduleTask as the sole task API and migrate the relationship input.
Represent callbacks as Task and rename their context to TaskContext.
BREAKING CHANGE: replace queueTask(fn, options) with
scheduleTask({ task: fn }). Move beforeProcess and afterProcess into
the task and handle rejected promises.
Every early exit from a submission is followed synchronously by the
finally block, which already restores processing and disabled state for
submissions that took them. Remove the duplicate per-branch releases.
Drop TaskContext.isQueueReset, which was always the negation of
isCurrent and had no callers.
Keep the existing method name and change only its signature to
queueTask({ priority, task }).

fix(ui): consolidate form requests into a single queue
fix(ui)!: consolidate form requests into a single queue
Nov 3, 2026
Autosave skips while a submitted form is invalid, reading validity from
field state that only updates when the form-state response arrives. The
check runs before that response, and once it marks the form valid the
values are unchanged, so autosave never fired again. On main, an
out-of-order form-state response masked this by clearing the error.
Retry the skipped autosave when the debounced form state next changes.
Every submission request now ends with an onChange form-state refresh,
which receives the successful submit response as `submitResponse`.
The Form no longer merges state returned from `onSuccess`, and the Edit
view builds its post-save state in onChange instead of onSave.
…sequencing-17455
Moves the single request queue onto Form-owned form-state requests.
- Form-state requests and submissions share the queue; the request after a successful submission runs inside the submission.
- A reset bumps the queue's generation instead of tracking request scopes in the Form, which removes requestScopeRef, unmountedRequestScopeRef and the superseded-submission release branch.
- reset() bumps the generation after its awaits, replaceState() resets the queue, and request state is restored after the context is replaced.
- The save stays successful when onSuccess resets the form; only the redirect is skipped once the form is no longer current.
- Serialized requests make the overlapping-save guard unnecessary.
