default values for each of the oneOf options are not displayed

General information

When a property is set as oneOf and each of the value option sets a default value, json-editor shows empty values either for the default option or switching to alternative options. Basically the default value settings are not used at all when oneOf is set.

Additionally, the title of the item is also fixed as the JSON key name, rather than using the title field of the property.

See below direct link to example

• json-editor version: 2.6.1

Expected behavior

for the default option (“string”), display the string-type default value “DP”, when switching to “integer”, sets to 5 instead

Actual behavior

choosing either option, the default value stays at empty

Steps to reproduce the behavior

{
  "title": "MCX JSON Input",
  "type": "object",
  "required": [
    "SaveDataMask"
  ],
  "format": "categories",
  "properties": {
    "SaveDataMask": {
      "oneOf": [
        {
          "title": "Save detected photon flags",
          "type": "string",
          "default": "DP"
        },
        {
          "title": "Save detected photon flags",
          "type": "integer",
          "default": 5,
          "minimum": 0
        }
      ]
    }
  }
}

on a side note - we wrote a web-GUI for a cloud-computing based simulator, where JSON editor was a key component in the frontend. This work was was recently published at https://doi.org/10.1117/1.JBO.27.8.083008, where we referenced the json-editor project. here is our web GUI: http://mcx.space/cloud/

json-editor really made our development much simpler, we want to thank the developers for your great works!

Thank you for the detailed response. I am using workaround no 1, because of a related issue. I choose a subschema in a anyOf and would like the defaults to be overwritten. As this does not work (it only overwrites changing properties) I can use your hack to force an initial selection.
