thanks for helping us!

well I am sure it doesn't call the factory I put a breakpoint there..

beforeI added @Scope(ScopeType.APPLICATION)
it did called the factory method but then I got NullPointerException 
you can see that in my first Post

here is the Codes code:

  | 
  | @Entity
  | @Scope(ScopeType.SESSION)
  | @Name("codes")
  | @Table(name="codes")
  | 
  | public class Codes  implements java.io.Serializable {
  | 
  | 
  |  // Fields    
  | 
  |   private int id;
  |   private String label;
  |   private String table;
  |   private String code;
  |   private String description;
  |   private Boolean disabled;
  | 
  | 
  |  // Constructors
  | 
  |  /** default constructor */
  |  public Codes() {
  |  }
  | 
  | 	/** minimal constructor */
  |  public Codes(int id, String table, String code) {
  |      this.id = id;
  |      this.table = table;
  |      this.code = code;
  |  }
  |  
  |  /** full constructor */
  |  public Codes(int id, String label, String table, String code, String description, Boolean disabled) {
  |      this.id = id;
  |      this.label = label;
  |      this.table = table;
  |      this.code = code;
  |      this.description = description;
  |      this.disabled = disabled;
  |  }
  |  
  | 
  | 
  |  // Property accessors
  |  @Id
  |  @Column(name="ID", unique=true, nullable=false, insertable=true, updatable=true)
  | 
  |  public int getId() {
  |      return this.id;
  |  }
  |  
  |  public void setId(int id) {
  |      this.id = id;
  |  }
  |  @Column(name="LABEL", unique=false, nullable=true, insertable=true, updatable=true, length=2000)
  | 
  |  public String getLabel() {
  |      return this.label;
  |  }
  |  
  |  public void setLabel(String label) {
  |      this.label = label;
  |  }
  |  @Column(name="TABLE", unique=false, nullable=false, insertable=true, updatable=true, length=200)
  | 
  |  public String getTable() {
  |      return this.table;
  |  }
  |  
  |  public void setTable(String table) {
  |      this.table = table;
  |  }
  |  @Column(name="CODE", unique=false, nullable=false, insertable=true, updatable=true, length=100)
  | 
  |  public String getCode() {
  |      return this.code;
  |  }
  |  
  |  public void setCode(String code) {
  |      this.code = code;
  |  }
  |  @Column(name="DESCRIPTION", unique=false, nullable=true, insertable=true, updatable=true, length=2000)
  | 
  |  public String getDescription() {
  |      return this.description;
  |  }
  |  
  |  public void setDescription(String description) {
  |      this.description = description;
  |  }
  |  @Column(name="disabled", unique=false, nullable=true, insertable=true, updatable=true)
  |   public Boolean getDisabled() {
  |      return this.disabled;
  |  }
  | 
  |  public void setDisabled(Boolean disabled) {
  |      this.disabled = disabled;
  |  }
  | }
