Describe the Bug

Relationship

So I have an relationship field which looks like this:

{
    admin: {
        position: "sidebar"
    },
    name: "userGroups",
    label: "Gebruikersgroepen",
    type: "relationship",
    relationTo: UserGroups.slug,
    localized: true,
    required: false,
    hasMany: true,
    index: true,
}

When I remove all the selected userGroups in de Admin panel and save the document it gives a green success toast, but it resets the relationship to the old value.

Some steps I took to test:

• Select 2 options, save -> ✅
• Deselect 1 option, 1 option remaining, save -> ✅
• Deselect 1 option, 0 options remaining, save -> 🚫 (although the toast message says success, it resets the selected options)

createParentField

I have another field, named parent, which is created by the createParentField.
When I query the collection, with that field, with ?where[parent][exists]=false it returns 0 docs, where it should have returned 2 docs.

?where[parent][exists]=true works however..

When it started

It started when I added localized: true. When I remove localized it works again, I can empty the field and query the collection successfully.

What happens here with localized: true?

To Reproduce

1. Create 2 collections
2. Add a relationship from one collection to the other with the following properties:
   • localized: true
   • required: false
   • hasMany: true
3. Go to admin panel
4. Add a couple docs in the 2 collections
5. Go to one doc, select a couple options in the relationship field
6. Save the doc
7. Edit the relationship field, remove all the selected docs
8. Save the doc
