    problems creating drop down menu using selectOneMenu

    sweet sonia Newbie

      Hello,

      I am new to seam. I've been trying to create a drop down menu in order to choose an entity "tipus" which is a foreign key of another entity "SLA".

      After consulting so many forums and tutorials I've been able to code it but the problem is that I'm not getting any "tipus" to choose from in the dropdown list.

      It just says "Select a Tipus".

      Can anyone please tell me where is the problem.

       

      A part of my SlaEdit.xhtml:

                                 noSelectionLabel="Select a tipus." />

                                 <s:convertEntity />

                    

                                 <f:ajax event="change" action="#{TipusActionBean.test()}" reRender="tipusField" />

                System.out.println("initTipusToTrack");

                return tipusToTrack;

          }

       

       

        

          public Tipus getSelectedTipus() {

                  log.info(">>>>> get selectedTipus");

                                          + this.selectedTipus.getIdTipus());

                  return this.selectedTipus;

          }

        

       

       

          public void setSelectedProfil(Tipus tipus) {

                  this.selectedTipus = tipus;

          }

                  System.out.println("test");

                  System.out.println(selectedTipus == null ? "null" : selectedTipus.getIdTipus());

          }
