File field in navigation blueprint resets preview when sidepanel closes

[mawalu]

Bug description

We have a file field to upload images in our navigation blueprint. When a user sets an image, saves the navigation item and reopens the navigation item side panel without reloading, the file field is no longer populated but defaults to the empty state.

After the tree is saved and the page reloaded the field is populated correctly but this behavior causes confusion to users.

How to reproduce

• Add a file field to a navigation blueprint
• Choose a file for a navigation item and save the item
• Click again on the same navigation item opening the side panel, without saving the tree or reloading first
• See that the file field is not showing your selected file as value

Happens both with newly uploaded files and existing files

Additional details

This issue already existed on previous versions, I just updated to verify it still affects the latest one

The "Files" fieldtype is only really intended to be used on forms and by addon developers. It only uploads the file, it doesn't actually handle storing it.

You should probably be using the Assets fieldtype instead.

Thank you for your response and sorry for the inaccuracy, but we are using a type: assets field for this. At least in the translated version of the CP the Fieldtype is called "Files" in the ui, thats why I referred to it that way.

-
  handle: headerimage
  field:
    max_files: 1
    container: images
    type: assets
    display: 'Headerbild'
    localizable: false

Can this be reopened?

This looks like the same underlying issue as #10630. When you re-open a nav item after saving, the preview isn't displayed. It works as expected after refreshing the page.

The issue affects all fields in the nav blueprint not just asset fields :/

nav_test.yaml

tabs:
  main:
    display: Main
    sections:
      -
        fields:
          -
            handle: assets_field
            field:
              container: assets
              type: assets
              display: 'Assets Field'
          -
            handle: replicator_field
            field:
              type: replicator
              display: 'Replicator Field'
              sets:
                new_set_group:
                  display: 'New Set Group'
                  sets:
                    new_set:
                      display: 'New Set'
                      fields:
                        -
                          handle: text_field
                          field:
                            type: text
                            display: 'Text Field'

The issue is that when you close the PageEditor.vue, the entire VueX state gets destroyed. This results in losing all the meta data.

This has been fixed in Statamic 6, which is due to be released ~Q3, with an alpha on its way in the next week or so. You can learn more about v6 on our blog.
