Array in query using $ref for items does not validate

[danjor]

For query parameter, using a type array and items property containing $ref to definition of the object is not validated.

swagger: "2.0"
info:
  version: 1.0.1

  /getSomething:
    get:
      operationId: getSomething
      parameters:
        - name: type
          in: query
          required: false
          type: array
          items:
            $ref: '#/definitions/myType'
      responses:
        default:
          description: unexpected error
          schema:
            type: string
definitions:
  myType:
    type: string
    enum: ["ab", "cd", "ef"]

I get that from validator :

{
  "schemaValidationMessages": [
    {
      "level": "error",
      "domain": "validation",
      "keyword": "oneOf",
      "message": "instance failed to match exactly one schema (matched 0 out of 2)",
      "schema": {
        "loadingURI": "http://swagger.io/v2/schema.json#",
        "pointer": "/definitions/parametersList/items"
      },
      "instance": {
        "pointer": "/paths/~1getSomething/get/parameters/0"
      }
    }
  ]
}

This doesn't work as well without enum property in the myType definition.

In my case, I need to define myType as an enum once, and refer to it from the parameter definition.

@danjor - that's not supported by the spec. See OAI/OpenAPI-Specification#300.
