title: TmongoDbInput schema not retrieving JsonArray Properly
body: <p>I'm trying to retrieve below mongo collection data using TalendOpenStudio for Big Data 7.2.
  T</p>
  
  <p>{
  "id": "5b69b66d3dae73000fa39440",</p>
  
  <p>"data":"Testing"
  "products": [{ "orderid":"1234"
  }],
  "createDate": "2018-08-07T15:10:37.570Z",
  "updateDate": "2018-08-09T16:09:46.621Z"
  } </p>
  
  <p>I'm able to get Id,data but when i try to get products i'm unable to get the data. On top of it i'm getting products as below</p>
  
  <p>[Document{{"orderid"="1234"}}] this is blocking me for parsing it as json. Can someone help. I think its a basic mistake but as i said i'm new to Talend OS for Big Data</p>
  
  <p>If anyone has already parsed this , can you please share the schema to be defined for products arraylist in talend and how they parsed id,data,products.</p>
  
  <p>I tried using extractjson fields, using mongoschema from repository still no luck.</p>
