[jboss-user] [JBoss Seam] - @DataModel problem

[lsabin]

Hi.

I have the following component which retrieves a list of courses done by a employee. This works fine but when I included some code to get a list of courses that match a certain input the list of courses is not retrieved (actually the method listCoursesEmployee()  is not invoked at all).


  | @Name("courseservice")
  | @Scope(ScopeType.CONVERSATION)
  | @Restrict("#{identity.loggedIn}")
  | public class CourseAction {
  |     
  |         
  |     @In
  |     private EntityManager entityManager;
  |     
  |     @In(value="empleadoSel")
  |     private Tecnico selectedEmployee;    
  |     
  | 
  |     @DataModel
  |     private List<CursoCurriculum> listCoursesEmployee = new ArrayList<CursoCurriculum>();
  |     
  |  
  |     
  |     public CourseAction(){}
  | 
  |     
  |  
  |     @Factory(value="listCoursesEmployee",autoCreate=true)
  |     public void listCoursesEmployee(){
  |         
  |         
  |         if (selectedEmployee != null)
  |         {    
  |             Curriculum cvEmpleado = null;
  | 
  |             cvEmpleado = selectedEmployee.getCurriculum();
  | 
  |             if (cvEmpleado != null)
  |                 listCoursesEmployee = cvEmpleado.getCursos();
  |         }
  |         
  |     }
  | 

But if I move the code that gets the list of courses to another component everything works. This is the code in the new component:

 

  | 
  | @Name("cursoservice")
  | @Scope(ScopeType.CONVERSATION)
  | @Restrict("#{identity.loggedIn}")
  | public class CursosAction {
  |     
  |         
  |     @In
  |     private EntityManager entityManager;
  |     
  |    
  |     private String nombreCurso;
  | 
  | 
  |     @Out(scope=ScopeType.EVENT)
  |     List<Curso> listaCursosParcial = new ArrayList<Curso>();
  |     
  |     public CursosAction(){}
  |     
  |     public List<Curso> getListaCursosParcial(){
  |         return listaCursosParcial;
  |     }
  |   
  | 
  |     public void setNombreCurso(String nombreCurso) {
  |         this.nombreCurso = nombreCurso;
  |     }
  | 
  |     
  | 
  |     public void obtieneCursosParcial(){
  |         
  |       		String patron = "";
  | 			patron = (nombreCurso == null) ? "%" : ('%' + nombreCurso.toLowerCase().replace('*', '%') + '%');
  |         
  |   listaCursosParcial = entityManager.createQuery(
  |                 "from Curso where LOWER(nombre) like :patron order by nombre")
  |                 .setParameter("patron",patron)
  |                 .getResultList();
  |     }
  | 

I want to have all the code in the first component. If this is posible what am I doing wrong?

Thanks.
