2. Re: Error selecting object
laksu May 2, 2007 3:03 AM (in response to laksu)In a form I fill values for an Istek object and use the combobox as a lookup for its member "gorevli". I expect this mechanism to assign the selected "Uzman" object to the member "gorevli".
No stacktrace, no exceptions.
Here is the corresponding action bean IsteklerAction. I have removed a lot for clarity:@Stateful @Name("isteklerAction") @Scope(ScopeType.SESSION) public class IsteklerAction implements Serializable, IsteklerActionLocal { @PersistenceContext(type=PersistenceContextType.EXTENDED) private EntityManager entityManager; public IsteklerAction() {} @DataModel private List<Istek> isteklerList; @In(required=false) @Out(required=false) private Istek istek; @Factory("isteklerList") public void refreshIstekler(){ System.out.println("refreshing istekler"); isteklerList=entityManager.createQuery("from Istek i order by acilis").getResultList(); } @Out private List<Uzman> uzmanlar; private void refreshUzmanlar(){ uzmanlar=entityManager.createQuery("from Uzman u").getResultList(); } public void refresh() { refreshIstekler(); refreshUzmanlar(); } public void save() { if (status=="N"){ entityManager.persist(istek); } else { istek=entityManager.merge(istek); } status="V"; refreshIstekler(); }
And the Istek class has a member named "gorevli" which is an "Uzman".@Name("istek") @Scope(ScopeType.PAGE) @Entity public class Istek implements Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; @ManyToOne private Uzman gorevli; ... }
Uzman extends Kullanici whis has the @Id field:@Entity @DiscriminatorValue(value="U") public class Uzman extends Kullanici { @OneToMany(mappedBy="gorevli") private java.util.List<Istek> gorevler; @ManyToMany(mappedBy="gorevliler") private Set<Proje> sorumluluklar; ... } ... @Entity @Name("kullanici") @Scope(ScopeType.CONVERSATION) @Role(name="login",scope=ScopeType.SESSION) @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name="turu",discriminatorType=DiscriminatorType.CHAR) @DiscriminatorValue(value="S") public class Kullanici implements java.io.Serializable { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; private String ad; private String adSoyad; private String parola; }
Best regards.

3. Re: Error selecting object
christian.bauer May 2, 2007 4:34 AM (in response to laksu)You said you get a "message". Where and from what?
-
4. Re: Error selecting object
waynebagguley May 2, 2007 4:41 AM (in response to laksu)Try adding an "equals" method to either Uzman or Kullanici that tests against the "id" field.
-
5. Re: Error selecting object
christian.bauer May 2, 2007 4:46 AM (in response to laksu)That is, no matter what the problem is, not a good idea. Equality based on database identity does not work (longest discussion threads on Hibernate forum, etc).

6. Re: Error selecting object
waynebagguley May 2, 2007 4:57 AM (in response to laksu)If it works at least it will help to track down the problem.

7. Re: Error selecting object
laksu May 2, 2007 10:58 AM (in response to laksu)Ok, I went through creating equals and hashcode methods for the Kullanici and Uzman as well. IMHO I have doen a decent implementation with commns-lang hashcode and equals builders.
Yet the problem is still there.
With "message" I mean a JSF message that can be seen by <h:messages/>. And the message is "Error selecting object"
This message is from the source :@Name("org.jboss.seam.ui.entityConverter") @Scope(ScopeType.CONVERSATION) @Install(precedence = BUILT_IN) @Converter @Intercept(NEVER) public class EntityConverter implements javax.faces.convert.Converter, Serializable { private ValueBinding<EntityManager> entityManager; private Log log = Logging.getLog(EntityConverter.class); private String errorMessage = "Error selecting object";

10. Re: Error selecting object
pmuir May 3, 2007 10:13 AM (in response to laksu)Seam CVS uses jboss-el not el-ri. seam-gen should create you a correct application, or take a look at one the examples.

11. Re: Error selecting object
laksu May 4, 2007 11:04 AM (in response to laksu)I have tried seam-gen. It does not produce a flawless project, I had to add some jars manually into the build.xml. and this is only the barebone application generated. (Shouls I submit an issue about it?)
