Changing identity title is not registered

[Jgfrausing]

Setting "This field represents the Entry title" under "Field options" is not reflected in the migration when no other changes are made to the field/content type.

I looked into the issue, and have found a possible cause.
Why are field and sys deleted from the object before diff is created?

const fromTypeDef = Object.assign({}, to)
delete(fromTypeDef.fields)
delete(fromTypeDef.sys)
const toTypeDef = Object.assign({}, to)
delete(toTypeDef.fields)
delete(toTypeDef.sys)

const typeDefDiff: DiffArray<IField> = diff(fromTypeDef, toTypeDef)
const fieldsDiff: DiffArray<IField> = diff(from.fields, to.fields)

@gburgett and @bsgreenb what's your thought on this?

Hi @Jgfrausing,

The answer is directly below that line, where we check to see if typeDefDiff has any changes. If it does, we pass the new values to the second parameter of editContentType. That parameter takes the following fields:

export interface IContentTypeOptions {
  /** Name of the content type. */
  name: string,
  /** Description of the content type. */
  description?: string,
  /** ID of the field to use as the display field for the content type. */
  displayField?: string
}

Note that "sys" and "fields" are not in that definition, so we ignore them for the purposes of that diff.

Now to your original issue, if you select that button, it should update the "displayField" property of the content type and therefore it ought to show up in the diff. Would you please provide two Contentful export JSON files of a content type that reproduces this issue? You can do this by exporting your space before checking the box, and then again after checking the box and hitting save on the content type.

Thank you,
Gordon

Hi @gburgett ,
Sorry for the delay. I've created a small sandbox env and changed the entry title field.
(Something went wrong in the process, so the field controls got changed as well)

The zipfile contains the states title.json and name.json and the diff output.
