allOf inside items doesn't work

• Description: Usage of allOf inside items only shows the first element
• Version: 2.1.4
• Example:

I'm trying to add an id field to user's definition. A part of my swagger.json file:

"docs": {
  "type": "array",
  "items": {
    "allOf": [
      {
        "$ref": "#/definitions/User"
      },
      {
        "properties": {
          "id": {
            "type": "string"
          }
        }
      }
    ]
  }
}

The example value showed in the ui is the following:

{
  "docs": [
    {
      "email": "string",
      "createdAt": "2016-07-12T19:40:42.290Z",
      "updatedAt": "2016-07-12T19:40:42.290Z"
    }
  ],
  "total": 0,
  "limit": 0,
  "offset": 0
}

As you can see, the id field is not shown. Any idea ? I would highly appreciate any help.
Thank you.
