[BUG] oneOf/required does not work correctly for golang

I have this yaml file:

openapi: 3.0.0
info:
  version: '1.0.0'
  title: 'Test'

paths: {}
components:
  schemas:
    Test:
      type: object
      oneOf:
        - required:
          - test1
        - required:
          - test2
      properties:
        normalField:
          type: string
        test1:
          $ref: '#/components/schemas/Test1'
        test2:
          $ref: '#/components/schemas/Test2'
        normalField2:
          type: string

    Test1: 
      type: object
      required:
        - a
        - b
        - c
      properties:
        a:
          type: int
        b:
          type: string
        c:
          type: string
    Test2:
      type: object
      required:
        - ab
        - bb
        - cc
      properties:
        aa:
          type: int
        bb:
          type: string
        cc:
          type: string

when I execute the generator for golang, then I receive this generated datatype:

// Test - struct for Test 
type Test struct {
    interface{} *interface{}
}

Is it possible to make this better, since basically it gives error and actually the fields are not included at all.

If I remove the oneOf, then it generates the correct datatype, but then I loose the checker functions. thanks Akos
