Hello,

I'm having some troubles trying to fill a @DataModelSelection.

My @DataModel works, the h:dataTable iterates fine, but when I choose a row it just reloads the page, but my selection continues empty.

I'll post my code above, please, any help will be very welcome.

Bean:

@Name("collaboration")


public class CollaborationHome 
{
          @In
    EntityManager entityManager;


          @Out(required = false, value="ontologies")
          List<Ontology> oL;


          @Factory("ontologies")
          public void getOntologies()
          {
                    oL =  (List<Ontology>) entityManager.createQuery("from Ontology").getResultList();
          }


          private Ontology ontology;
  
          public Ontology getOntology()
          {
                    return ontology;
          }
  
          public void setOntology(Ontology ontology)
          {
                    this.ontology = ontology;
          }
  
          @DataModel
          private List<Universal> universals;
  
          @DataModelSelection("universals")
          @Out(required=false)
          private Universal selectedUniversal;
  
          public void getSelectedUniversal(Universal selectedUniversal)
          {
                    this.selectedUniversal = selectedUniversal;
          }
  
          public Universal getSelectedUniversal()
          {
                    return selectedUniversal;
          }
  
          @Factory("universals")
          public void selectUniversals()
          {
                    {
                              universals = (List<Universal>)entityManager.createQuery("from Universal where unty_id=1 and onto_id = :ontoid").
                                                                                                         setParameter("ontoid", ontology.getOntoId()).
                                                                                                         getResultList();
                    }
          }

    }

</ui:composition>

As I said, the drop down menu is populated, the load button works fine, then the universal query work aswell, but when I select a universal using the commandLink nothing happens, the page reloads but selectedUniversal still empty.

I've tried the s:link also, but when the page reloads ontologies becomes null and then I get an error.

I have no idea what to do, followed every step of the book but still doesn't work =\
