I dont know why my dataTable does not sort the columns when i click on the sort arrow. It only works if i first type something on the filter and erase it.(It is like it needs to have at least one character on the filter to be able to sort correctly).
I will paste the code here:
This is the JSF page with the dataTable
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<p:dataTable var="garbage" value="#{resultsController.allGarbage}" dynamic="true" paginator="true" paginatorPosition="bottom" rows="10"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="5,10,15">
<p:column filterBy="#{garbage.filename}" filterMatchMode="startsWith" sortBy="#{garbage.filename}" parser="string">
<f:facet name="header">
<h:outputText value="Filename" />
</f:facet>
<h:outputText value="#{garbage.filename}" />
</p:column>
<p:column filterBy="#{garbage.description}" filterMatchMode="contains">
<f:facet name="header">
<h:outputText value="Description" />
</f:facet>
<h:outputText value="#{garbage.description}" />
</p:column>
<p:column sortBy="#{garbage.uploadDate}" parser="string">
<f:facet name="header">
<h:outputText value="Upload date" />
</f:facet>
<h:outputText value="#{garbage.uploadDate}" />
</p:column>
</p:dataTable>
</h:form>
</ui:define>
Here the managed bean that interacts with that page:
@ManagedBean
@ViewScoped implements Serializable
public class ResultsController {
@EJB
private ISearchEJB searchEJB;
private Garbage garbage;
public List<Garbage> getAllGarbage() {
return searchEJB.findAllGarbage();
}
public Garbage getGarbage() {
return garbage;
}
public void setGarbage(Garbage garbage) {
this.garbage = garbage;
}
The EJB that accesses the database:
@Stateless(name = "ejbs/SearchEJB")
public class SearchEJB implements ISearchEJB {
@PersistenceContext
private EntityManager em;
public List<Garbage> findAllGarbage() {
Query query = em.createNamedQuery("findAllGarbage");
List<Garbage> gList = new ArrayList<Garbage>();
for (Object o : query.getResultList()) {
Object[] cols = (Object[]) o;
Garbage tmpG = new Garbage();
tmpG.setFilename(cols[0].toString());
tmpG.setDescription(cols[1].toString());
tmpG.setUploadDate(cols[2].toString());
gList.add(tmpG);
}
return gList;
}
}
The entity with the JPQL named query being used:
@NamedQuery(name = "findAllGarbage", query = "SELECT g.filename, g.description, g.uploadDate FROM Garbage g;")
@Entity
public class Garbage implements Serializable{
@Id
@GeneratedValue
@Column(nullable = false)
private Long id;
@Column(nullable = false)
private String filename;
@Column(nullable = false)
private String fileType;
@Column(nullable = false)
private String uploadDate;
@Column(nullable = false)
private String destroyDate;
@Lob
@Column(nullable = false)
private byte[] file;
@Column(nullable = false)
private String description;

I would like to confirm that I experience exactly the same problem described with primefaces-2.2.1.
The value (row elements) of my dataTable are computed from a query.
Sorting on a simple name String property fails unless I also have a filterBy, and even then it only works if I type in at least one letter into the filter box. Then I can sort ascending/descending within the filtered result.
