    s:selectItems and s:convertEntity

    Fritz Gaschler Newbie

      Hi!


      i tried to put in a component into my jsf page! suddenly many obstacles came into my way. after a while i figured out how to come along with this issue but i have some questions.



      well i have an entity representing a location and another entity which describes a locationType and the address entity  holding the address for the specific location.


      @Entity
      public class Location {
      
           private Long id;
           private String name;
           private Address address;
           private String description;
           private LocationType locationType;
      
              @OneToOne(cascade = CascadeType.ALL)
              @JoinColumn(name="address_fk")
           public Address getAddress() {
                return address;
           }
              @OneToOne
              @JoinColumn(name="locationType_fk")
           public LocationType getLocationType() {
                return locationType;
           }
      





      @Entity
      public class LocationType {
      
           private Long id;
           private Location location;
           private String locationType_de;
           private String locationType_en;
      
              @OneToOne(mappedBy = "locationType")
              public Location getLocation() {
              return location;
              }
      



      @Entity
      public class Address {
      
          private Long id;
          private String countryNameCode;
          private String administrativeAreaName;
          private String subAdministrativeAreaName;
          private String localityName;
          private String thoroughfareName;
          private String postalCodeNumber;
          private GLatLng coordinates;
          private User user;
          private Location location;
      
          @OneToOne(mappedBy = "address")
          public User getUser() {
           return user;
          }
           
          @OneToOne(mappedBy = "address")
          public Location getLocation() {
           return location;
          }
      



      furthermore i have written down a form and i want to display the different types of locations in a dropdown box. this actually works. i did this way that i fill a list with locationtype objects and add the objects attributes either englisch or german to a list of the type SelectItems to pass it to the page...


      but i dont know how to merge the chosen value from the selectonemenu back to an object.


      or is there an easier way!?



      public ArrayList<SelectItem> getLocationType() {
      
                types = em.createQuery("Select type from LocationType type").getResultList();
      
                for (LocationType loc : types) {
                     locationType.add(new SelectItem(loc.getLocationType_de()));
                }          
                return locationType;          
           }





      anybody an idea!?
