Description

Prerequisites

What theme are you using?

core

Version

5.x

Current Behavior

When one of the options from anyOf/oneOf is rendered, the default values get set properly. However, after you switch to a different option, then go back, all the defaults will be gone.

Expected Behavior

The defaults should get set every time someone changes the subschema version

Steps To Reproduce

  1. Go to https://rjsf-team.github.io/react-jsonschema-form/
  2. Click the "Any Of" example
  3. Notice that "First method of identification" is selected, and "First name" is set to the default value, "Chuck"
  4. In the render view, change to "Second method of identification"
  5. In the render view, change to "First method of identification"

Current: "First name" is empty Expected: "First name" is set to the default value, "Chuck"

Environment

- OS: Windows 11
- Node & npm: whatever you use on your playground

Research direction
Investigate the logic that handles reinitializing form data when switching between anyOf/oneOf subschemas. The issue is reproducible in the official playground under the 'Any Of' example. Look at the code that sets default values when a subschema is selected, and ensure defaults are reset upon each switch. Files likely involved are those handling subschema selection and form data reset, possibly in the `@rjsf/core` package.
