BUG: Deleting one custom field clears the entire custom fields list

[jmbillard]

Summary

Deleting a custom field causes all custom fields to disappear from the Custom Fields administration page.

Environment

• Windshift self-hosted
• Docker deployment

Steps to Reproduce

1. Open Administration/System Settings.
2. Navigate to Content & Structure → Custom Fields.
3. Create multiple custom fields.
4. Delete one of the custom fields.
5. Return to the Custom Fields list.

Actual Behavior

After deleting a custom field, all custom fields disappear from the Custom Fields administration page.

The existing custom fields are no longer visible in the configuration list, even though only a single field was deleted.

Expected Behavior

Deleting one custom field should only remove that specific field.

All remaining custom fields should continue to be displayed and available for configuration.

Additional Information

The issue seems to affect the custom fields listing after a delete operation.

The deletion action appears to trigger an incorrect refresh or state update, causing the entire custom field list to become empty.

Possible Cause

Possible issues include:

• The frontend state is not being refreshed correctly after deletion.
• The delete operation invalidates or clears the entire custom fields collection.
• The API response after deletion is not being handled correctly.
• A failed reload causes the UI to display an empty list.

Request

Please verify the custom field deletion flow:

• Deleting a single custom field.
• Refreshing the custom field list after deletion.
• Preserving existing custom field configurations.

Thanks!

After deleting the custom field, I noticed another related issue: the Default Screen configuration where the field was assigned became empty.

All fields that were previously configured on that screen disappeared. Additionally, some system fields were no longer available in the sidebar list to be added again (for example, the Title field).

A workaround I found:

1. Drag any available field item from the right sidebar into the empty screen configuration list.
2. Save the screen configuration.

After saving, the screen seems to reset correctly:

• The field items become available again in the configuration sidebar.
• The remaining custom fields (the ones that were not deleted) reappear.
• The system fields become available/visible again.

I also noticed another inconsistency: if the deleted custom field was configured to be displayed on cards, it is not removed from the card field visibility configuration. It remains listed as something like:

custom_field_[index based on creation order]

even though the custom field itself no longer exists.

It looks like deleting a custom field is leaving stale references in screen configurations and card field visibility settings.
