Spring data custom N1QL query returns property document to null
<p>I'm using <code>spring-data-couchbase 2.1.2</code>, I redefined a repository with a custom query:</p>

<pre><code>@Override
public List&lt;PortfolioDocument&gt; searchPortfolio() {

    CouchbaseOperations template = templateProvider.resolve(PortfolioRepository.class, PortfolioDocument.class); 

    String statement = "select META(ipdb).id AS _ID, META(ipdb).cas AS _CAS, * " + 
        "from ipdb where _class = 'com.ipdb.datamodel.document.PortfolioDocument' AND  title = 'dummytitle'";
    SimpleN1qlQuery query = N1qlQuery.simple(statement);;
    List&lt;PortfolioDocument&gt; portfolioDocuments = template.findByN1QL(query, PortfolioDocument.class);

    ....
}
</code></pre>

<p><code>template.findByN1QL(query, PortfolioDocument.class);</code> returns some <code>PortfolioDocument</code> with all property to null except the id property.
If I call <code>template.findByOne(id);</code> the resulting object is ok.
Can you help me, please?</p>
