Describe the bug

Related to next branch.

Following input:

{
  "type": "object",
  "definitions": {
    "icon": {
      "type": "string"
    }
  },
  "properties": {
      "default_icon": {
          "anyOf": [
              {
                  "type": "string",
                  "description": "FIXME: String form is deprecated."
              },
              {
                  "type": "object",
                  "description": "Icon for the main toolbar.",
                  "properties": {
                      "19": {
                          "$ref": "#/definitions/icon"
                      },
                      "38": {
                          "$ref": "#/definitions/icon"
                      }
                  }
              }
          ]
      }
  }
}

Expected behavior

Generates a model where only an object is possible, and not string.

This problem occurs as part of draft-4 chrome-manifest.json blackbox test.

Seems to be fixed by #899 as it generates:

class Root {
  private _defaultIcon?: string | DefaultIconAnyOf_1;
  private _additionalProperties?: Map<string, any>;

  constructor(input: {
    defaultIcon?: string | DefaultIconAnyOf_1,
    additionalProperties?: Map<string, any>,
  }) {
    this._defaultIcon = input.defaultIcon;
    this._additionalProperties = input.additionalProperties;
  }

  get defaultIcon(): string | DefaultIconAnyOf_1 | undefined { return this._defaultIcon; }
  set defaultIcon(defaultIcon: string | DefaultIconAnyOf_1 | undefined) { this._defaultIcon = defaultIcon; }

  get additionalProperties(): Map<string, any> | undefined { return this._additionalProperties; }
  set additionalProperties(additionalProperties: Map<string, any> | undefined) { this._additionalProperties = additionalProperties; }
}
class DefaultIconAnyOf_1 {
  private _number_19?: string;
  private _number_38?: string;
  private _additionalProperties?: Map<string, any>;

  constructor(input: {
    number_19?: string,
    number_38?: string,
    additionalProperties?: Map<string, any>,
  }) {
    this._number_19 = input.number_19;
    this._number_38 = input.number_38;
    this._additionalProperties = input.additionalProperties;
  }

  get number_19(): string | undefined { return this._number_19; }
  set number_19(number_19: string | undefined) { this._number_19 = number_19; }

  get number_38(): string | undefined { return this._number_38; }
  set number_38(number_38: string | undefined) { this._number_38 = number_38; }

  get additionalProperties(): Map<string, any> | undefined { return this._additionalProperties; }
  set additionalProperties(additionalProperties: Map<string, any> | undefined) { this._additionalProperties = additionalProperties; }
}
