Fieldtype field()->parent() populated with wrong entry

[naabster]

Bug description

Since 4.51.0 the field()->parent() is set to some other entry.

I have a custom fieldtype which needs the entry id to populate data from an API. I do this in the preload() method using $this->field()->parent() Since 4.51.0 this resolves some random entry, but not the correct one. Most of the time the last entry in the structure tree (I noticed the bug in a structured collection).

How to reproduce

Use a custom fieldtype and check the parent:

<?php

namespace App\Fieldtypes;

use Statamic\Fields\Fieldtype;

class Sections extends Fieldtype
{
    public function preload()
    {
        ray($this->field()?->parent());
        ray($this->field()?->parent()->id());

        $parentEntry = $this->field()?->parent()->id();
        self::appendConfigField('parent_entry', [
            'type' => 'text',
            'default' => $parentEntry,
        ]);
        return ['parent_entry' => $parentEntry];
    }
}

I've just tested this in my sandbox site and wasn't able to replicate the issue 🤔

Where were you seeing the wrong entries being populated - in the entry publish form?

@duncanmcclean it took me a while to narrow it down further: i could replicate the issue in a fresh install with a structured collection with dates enabled. So both structure and publish dates need to be enabled. Also use a proper cache driver (like redis), not the array cache driver!

Collection:

title: testcollection
template: default
layout: layout
revisions: false
date: true
sort_dir: asc
date_behavior:
  past: public
  future: private
preview_targets:
  -
    label: Entry
    url: '{permalink}'
    refresh: true
structure:
  root: true
  max_depth: 3

Blueprint:

title: testcollection

  main:

              required: true
              validate:

App/Fieldtypes/ParentTest.php

<?php

namespace App\Fieldtypes;

use Statamic\Fields\Fieldtype;

class ParentTest extends Fieldtype
{
    public function preload()
    {
        $parentEntry = $this->field()?->parent()->id();
        self::appendConfigField('parent_entry', [
            'type' => 'text',
            'default' => $parentEntry,
        ]);
        return ['parent_entry' => $parentEntry];
    }
}

resources/js/components/ParentTest.vue

<template>

    <div>
        <p>ID: {{ config.parent_entry }}</p>
    </div>

</template>

<script>
export default {

    mixins: [Fieldtype],

    data() {
        return {
            //
        };
    }

};
</script>

You would expect that the ID shown on the publishing form is the ID of the entry. On the first page load after clearing cache and stache it more or less is, afterwards it is some other ID. So if your collection only has one entry everything is fine 🤷
