I’m having trouble formatting a datatable with a fixed column and x variable columns.
POJO
@Entity
@Table(name="avaliaprojeto", schema="somore")
public class AvaliaProjeto implements Serializable, SampleEntity {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int idAvaliaProjeto;
@OneToOne
@JoinColumn(name="idProjeto")
private Projeto projeto;
@OneToOne
@JoinColumn(name="idCriterio")
private Criterio criterio;
@OneToOne
@JoinColumn(name="idEscala")
private Escala escala;
double valorCriterio;
//gets sets equals e hash
}
There is a list of objects Avaliaprojeto, several linked to the same project. This object aims to relate Criterion-Scale. The goal is to present in a datatable in the following format:
However, when I enter more than one project, the formatting is changed to:
Realize that they are Evaluative objects that deal with exactly the same criteria, varying only their impacts/values.
The view used to create these templates and to register (via dialog) is:

If you need anything else, please let me know.
your method
topsisBean.avaliaProjetosreturns what exactly?– Maicon Carraro
A list of objects of the Avaliaprojeto type.
– HDeiro
In this case, each row of this table is equivalent to five records in the database. That is, I believe that the problem with two columns is due to the fact that this method returns ten records from the database (5 referring to each project). Only nine appear due to the fact that Project is outside the <p:Columns>
– HDeiro
actually on that
valueyou should return only the columns and not the list with the objects, take a look at this example here– Maicon Carraro
Got it. The problem is that if I put the list of objects in the datatable it will get a lot of unwanted lines. Each project has 5 objects evaluatedProject. Have any idea what you can do?
– HDeiro
If you look at the link I sent it actually has 2 different lists, one for the columns and the other with the data
– Maicon Carraro
But that’s it. The thing is, in my case, there are three lists. One (number of rows) is the projects, one is the columns and the other is the column values. : p
