Property with reference is not rendered

[KIC]

Describe the bug

While the address renders fine, given the json schema below, the parent does not render at all.

type: "object",
definitions: {
  Client: {
      "address": {
          "type": "array",
          "items": {
              "$ref": "#/definitions/Address"
          }
      },
      "parent": {
          // https://jsonforms.io/docs/tutorial/multiple-forms#interlinked-inputs
          "$ref": "#/definitions/SearchableObject/properties/a_very_special_field"
          //"$ref": "#/definitions/SearchableObject"
          //"type": "object"
          //items: {"$ref": "#/definitions/SearchableObject"}
          //item: {"$ref": "#/definitions/SearchableObject"}
      }
  },
  SearchableObject: {
      "type": "object",
      "properties": {
          "a_very_special_field": {
              "type": "integer"
          }
      },
      "required": []
  },
 properties: {
    "Client": {
        "$ref": "#/definitions/Client"
    }
}

As soon as I turn the parent into an array field just like the address it renders fine again (but of course is an array which is not what I need).

Expected behavior

Render the Sub-Form for the parent object like for array fields

Steps to reproduce the issue

Render form using the jsonschema above und leave the uischema undiefined.

Hi @KIC,

The posted schema is invalid and/or incomplete. For example the Client is not a valid JSON Schema. address also seems to point to a non-existing Address.

I adjusted it to the following

{
  "type": "object",
  "definitions": {
    "Client": {
      "type": "object",
      "properties": {
        "address": {
          "type": "array",
          "items": {
            "$ref": "#/definitions/Address"
          }
        },
        "parent": {
          "$ref": "#/definitions/SearchableObject/properties/a_very_special_field"
        }
      }
    },
    "Address": {
      "type": "string"
    },
    "SearchableObject": {
      "type": "object",
      "properties": {
        "a_very_special_field": {
          "type": "integer"
        }
      },
      "required": []
    }
  },
  "properties": {
    "Client": {
      "$ref": "#/definitions/Client"
    }
  }
}

Then I was able to reproduce the problem: The "parent" is not rendered. The error seems to be the same as reported here. As noted in the link, the problem is that the MaterialObjectRenderer does not hand over enough context to the UI Schema generator to successfully resolve the reference to the a_very_special_field.

This needs to be fixed. Contributions welcome!
