Form with array of objects automatically added with array of itself with Ids suffix

[Tanapruk]

What you were expecting:

Clicking save after editing should send like.

{
 categories: [{
"id": "1234",
"name": "nice"
}]
}

What happened instead:
Clicking save after editing should send like.
a new field called categoriesIds are magically added and fail my graphql

{
 categories: [{
"id": "1234",
"name": "nice"
}],
categoriesIds: ["1234"]
}

Steps to reproduce:
It happened after upgrading to 3.0.0. My best guess is the react-final-form automatically created the params with Ids suffix, since it shows the ids inside . I try to create a new fields with array of objects but that do not show the problems.

For now, I fix it by removing fields with ids suffix at the dataProvider.

Environment

• React-admin version: 3.0.1
• Last version that did not exhibit the issue (if applicable): 2.98
• React version: 16.8
• Browser: Chrome
• Stack trace (in case of a JS error):

@Tanapruk, This is normal work and React-admin feature.
Why does your GraphQL not work? I use GraphQL-Yoga for the backend and this solution not only does not break, but also helps in development.

However, there is one problem that I described here. The React-admin also converts my JsonInput in the same way, which sends a custom data object to the Provider.
@djhi, what do you think about this?

@wmwart I guess my problem is similar to yours but I couldn't make a minimum project to reproduce it right now.
