Aapo Laakkio 794bf8299c fix(next): version diff view shows correct document title in step nav (#13713)
This PR fixes two bugs in the version diff view SetStepNav component

### Bug 1: Document title isn't shown correctly in the step navigation
if the field of `useAsTitle` is nested inside a presentational field.

The StepNav shows the title of the document consistently throughout
every view except the version diff view. In the version diff view, the
document title is always `[Untitled]` if the field of `useAsTitle` is
nested inside presentational fields. Below is a video demo of the bug:


https://github.com/user-attachments/assets/23cb140a-b6d3-4d39-babf-5e4878651869

This happens because the fields of the collection/global aren't
flattened inside SetStepNav and thus the component is not accessing the
field data correctly. This results in the title being `null` causing the
fallback title to be shown.

### Bug 2: Step navigation shows the title of the version viewed, not
the current version

The StepNav component takes the title of the current version viewed.
This causes the second part of the navigation path to change between
versions which is inconsistent between other views and doesn't seem
intentional, although it could be. Below is a video of the bug with the
first bug fixed by flattening the fields:


https://github.com/user-attachments/assets/e5beb9b3-8e2e-4232-b1e5-5cce720e46b9

This happens due to the fact that the title is taken from the
`useAsTitle` field of the **viewed** version rather than the **current**
version. This bug is fixed by using the `useDocumentTitle` hook from the
ui package instead of passing the version's `useAsTitle` data down the
component tree. The final state of the step navigation is shown in the
following video:


https://github.com/user-attachments/assets/a69d5088-e7ee-43be-8f47-d9775d43dde9

I also added a test to test that the title part in the step navigation
stays consistent between versions and implicitly also tests that the
document title is shown correctly in the step nav if the field of
`useAsTitle` is a nested inside a presentational field.

Payload is the first-ever Next.js native CMS that can install directly in your existing /app folder. It's the start of a new era for headless CMS.

Benefits over a regular CMS

  • Deploy anywhere, including serverless on Vercel for free
  • Combine your front+backend in the same /app folder if you want
  • Don't sign up for yet another SaaS - Payload is open source
  • Query your database in React Server Components
  • Both admin and backend are 100% extensible
  • No vendor lock-in
  • Never touch ancient WP code again
  • Build faster, never hit a roadblock

Quickstart

Before beginning to work with Payload, make sure you have all of the required software.

pnpx create-payload-app@latest

If you're new to Payload, you should start with the website template (pnpx create-payload-app@latest -t website). It shows how to do everything - including custom Rich Text blocks, on-demand revalidation, live preview, and more. It comes with a frontend built with Tailwind all in one /app folder.

One-click templates

Jumpstart your next project by starting with a pre-made template. These are production-ready, end-to-end solutions designed to get you to market as fast as possible.

🌐 Website

Build any kind of website, blog, or portfolio from small to enterprise. Comes with a fully functional front-end built with RSCs and Tailwind.

We're constantly adding more templates to our Templates Directory. If you maintain your own template, consider adding the payload-template topic to your GitHub repository for others to find.
