Persisting JSON Creating List Objects

Good afternoon guys,

I'm having a question, I'm trying to persist a JSON via the API:

{
 ...
        "Analise": [{
            "nProcAnalitic": "SR-000446/2015",
            ...
        }]
...
}

And the service answers 200:

...
  "Analise": [
    {
      "id": null,
      "lotEntity": null,
      "nProcAnalitic": "SR-000446/2015"
...

But without creating the object of the listing, only the parent object.

Mapping:

@JsonProperty ("Analyze") @OneToMany (mappedBy="lotEntity") private List analysis;

...

@ManyToOne @JoinColumn (name="id_lot") private LotEntity lotEntity;
