[UsainBloot]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• 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?

core

Version

5.x

Current Behavior

When liveOmit and omitExtraData options are enabled, then you are unable to add a new item to an object that uses additionalProperties within an anyOf or oneOf.

Example json schema

{
  "oneOf": [
    {
      "type": "object",
      "additionalProperties": {
        "foo": {
          "type": "string"
        }
      }
    }
  ]
}

RJSF options

liveOmit: true
omitExtraData: true

Expected Behavior

Can add new items

Steps To Reproduce

1. Visit playground
2. Try and add a new item

Environment

Playground

Anything else?

Thanks for the report, @UsainBloot. We should probably not remove properties from objects that allow additionalProperties when omitExtraData is true.

We maintainers have limited time to get to all of the issues, so would you be interested in looking into fixing this?

Hi @nickgros, I think this PR would solve the issue
#3714

As it seems related to #3711 and #4314
