Spring/Hibernate not persisting all data submited from HTML Form - spring

Question

In my current spring pŕoject, I have a form like that:
<form role="form" class="form" id="form" method="post" action="/loja/pagina/insert" enctype="multipart/form-data">
<input class="form-control" type="hidden" name="id" />
<label>Title</label>
<input class="form-control" type="text" name="titulo" />
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active">
pt-BR
</li>
<li role="presentation">
es-ES</li>
<li role="presentation">en-US</li>
</ul>
<div class="tab-content">
<div role="tabpane1" class="tab-pane active" id="pt-BR">
<input type="hidden" name="textos.idioma" value="pt-BR" />
<textarea class="summernote" name="textos.conteudo"></textarea>
</div>
<div role="tabpane1" class="tab-pane" id="es-ES">
<input type="hidden" name="textos.idioma" value="es-ES" />
<textarea class="summernote" name="textos.conteudo"></textarea>
</div>
<div role="tabpane1" class="tab-pane" id="en-US">
<input type="hidden" name="textos.idioma" value="en-US" />
<textarea class="summernote" name="textos.conteudo"></textarea>
</div>
</div>
</form>
When I submit this form to this methods:
controller
#RequestMapping(value = "/insert", method=RequestMethod.POST)
#ResponseBody
#PreAuthorize("hasPermission(#user, 'insert_'+#this.this.name)")
public void insert(#Valid E object, BindingResult result) {
serv.insert(object);
}
service
#Transactional
public void insert(E object) {
dao.insert(object);
}
dao
#Transactional
public void insert(E object) {
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
session.persist(object);
tx.commit();
} catch (Exception e) {
if(tx != null)
tx.rollback();
} finally {
session.close();
}
}
Only the field titulo is persisted. the field textos , which is represented by this entity class (getters and setter omitted):
#Entity
public class Texto extends Model {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
#Column
private String idioma;
#Column
private String conteudo;
}
is not saved on the database. Anyone can tell what's the right way to implement the form to properly store this data? I check the browser's developer tools, and the data is being submitted, it's only not being persisted in the database.

Answer 1

I assume, that your model class Texto has a #OneToMany relation to class E, so that one E references multiple instances of Texto. If this is what your model expresses, you have to use a different syntax for your textarea names to Spring being able to parse your request payload.
In your case Spring would search for a property textos.conteudo on your class E. As I assume, that textos will be a collection, Spring will ignore this.
Assuming, that textos will be modeled as an indexed based collection like List, try to rename your textareas names to name="textos[0].conteudo" and so on to tell Spring that textos is a List and Spring will be able to parse the POST payload.

Answer 2

With the hint given to me by the user #AnsgarSchulte in this question, I change the html code in the form for name="textos[0] and change my PropertyEditorSupport class to handle this array and return a Texto object with the property idioma being the first element of the vector and the property conteudo being all the elements left (concatenating all of them in one string).
