    @DataModel problem

      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.
