Prerequisites

• I have searched the existing issues

• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

Version

Current Behavior

Using this json Schema

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "ExecuteMsg",
  "oneOf": [
    {
      "type": "object",
      "required": [
        "increment"
      ],
      "properties": {
        "increment": {
          "type": "object"
        }
      },
      "additionalProperties": false
    },
    {
      "type": "object",
      "required": [
        "reset"
      ],
      "properties": {
        "reset": {
          "type": "object",
          "required": [
            "count"
          ],
          "properties": {
            "count": {
              "type": "integer",
              "format": "int32"
            }
          }
        }
      },
      "additionalProperties": false
    }
  ]
}

when form is first initialized formData is {increment: {}} and when I change to reset formData is set to {increment: undefined, reset: {}} and again when change to increment formData is {increment: undefined, reset: undefined}

Expected Behavior

When changing back to option increment It should be {increment: {}} not {increment: undefined, reset: undefined}

Looks like a duplicate of #3711 ?

Thank you @nickgros for reading my issue
But I'm afraid the behavior #3711 is different from my behavior.

The current behavior I've mentioned is when changing back to oneOf element which requires empty object property results undefined value.
So for example I want a formData that have empty value(e.g {increment: {}} on submit. The initial formData when Form first renders is set as exactly what I wanted it to be({increment: {}}). But changing to other oneOf element and changing back to increment element will set the formData to {increment: undefined, reset: undefined} not {increment: {}, reset: undefined}.

I wish this information would helps you understand
