namespaces (nested) fields are not handled properly when of MongoDB type ReferenceField

[tafaust]

Hey,

I have the following fully dockerized setup: mongo-connector is up and running, keeping MongoDB and Elasticsearch in-sync (thanks at this point!). The configuration looks as follows:

   "mainAddress": "mongodb://mongodb:27017",
   "oplogFile": "/var/log/mongo-connector/oplog.timestamp",
   "noDump": false,
   "batchSize": -1,
   "verbosity": 2,
   "continueOnError": false,
   "namespaces": {
      "db.language": true,
      "db.tag": {
         "includeFields": ["name"]
      },
      "db.blogpost": {
         "includeFields": ["name", "content", "languages", "tags.name"]
      },
      "db.user": {
         "includeFields": ["username", "description"]
      },
      "db.comment": {
         "includeFields": ["text"]
      }
   },
   "logging": {
      "type": "file",
      "filename": "/var/log/mongo-connector/mongo-connector.log",
      "format": "%(asctime)s [%(levelname)s] %(name)s:%(lineno)d - %(message)s",
      "rotationWhen": "D",
      "rotationInterval": 1,
      "rotationBackups": 10
   },
   "docManagers": [
      {
         "docManager": "elastic2_doc_manager",
         "targetURL": "elasticsearch:9200"
      }
   ]
}

In this scenario, the document Tag is implemented in the blogpost as follows tags = ListField(ReferenceField('Tag')). The ReferenceField hence does not have an attribute name and thus "tags.name" is not getting synced to Elasticsearch.

Do you need more information on this issue? Or any ideas? I am looking forward your answer, thanks!
