enum of objects

Hi all,

I have following definition:

"CmDocumentDTO": {
  "type": "object",
  "required": [
    "docKey",
    "document"
  ],
  "properties": {
    "docKey": {
      "type": "integer",
      "format": "int32",
      "description": "ID of doc"
    },
    "document": {
      "type": "string",
      "description": "document name"
    },
    "typDok": {
      "$ref": "#/definitions/CmDocumentTypeEnum",
      "enum": [
        {
          "code":"W",
          "description":"MS Word"
        },
        {
          "code":"E",
          "description":"MS Excel"
        }
      ],
      "description": "doc type"
    }
},

"CmDocumentTypeEnum":{
  "type": "object",
  "properties": {
    "code": {
      "type": "string"
    },
    "description": {
      "type": "string"
    }
  }
},

And I want to generate source code via:

swagger-codegen-maven-plugin version 2.3.1

and I'm not able generate proper enum type, codegene create

public class CmDokumentTypdokEnum

instead java enum.

Can you help me please?
