 Post subject: Trouble with mapping a map

Hi all,

I'm at my wits' end on this one. I'm trying to map a simple map relationship between two entities. The foreign key for the owner is part of the primary key for the owned entity (which is typical).

Using Hibernate 3.2.5

Here are the class excerpts:

Code:
@Entity @Table(name="tip_action") @IdClass(TipActionId.class)
public class TipAction extends AbstractModelObject {
   @Id
   @Column(name="tip_name")
   private String tipName = null;

   @Column(name="action_type")
   @Enumerated(EnumType.STRING)   
   private ActionType actionType = null;
   
   @Column(name="date")
   private Date date = null;
   
   @Id
   @Column(name="person_id", nullable=false, insertable=false, updatable=false)
   private Long personId;
   
   @ManyToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER, optional=false)
   @JoinColumn(name="person_id", nullable=false)
   private Person person;
....
}


@Entity @Table(name="person")
public class Person extends AbstractModelObject {
   
   @Id @GeneratedValue(strategy = GenerationType.AUTO)
   private Long id = null;
   
   @Column(name = "customer_id")
   private Integer customerId = null;
   
   @MapKey(name="tipName")
   @OneToMany(fetch=FetchType.EAGER, mappedBy="person", cascade=CascadeType.ALL)
   private Map<String, TipAction> tipActions = new HashMap<String, TipAction>();
...
}

public class TipActionId extends AbstractModelObject implements Serializable {
   @Column(name="person_id")
   Long personId;   
   
   @Column(name="tip_name")
   String tipName;
...
}

This works for retrieval of existing data, but when I try to insert a new Person with a TipAction in the mapping, I get this error:

Code:
/* insert poscore.model.TipAction */ insert into tip_action (action_type, date, person_id, tip_name) values (?, ?, ?, ?)
[dino] WARN [main] JDBCExceptionReporter.logExceptions(77) | SQL Error: 0, SQLState: S1009
[dino] ERROR [main] JDBCExceptionReporter.logExceptions(78) | Parameter index out of range (5 > number of parameters, which is 4).


The query looks correct - that's the right number of fields for the table. But for some reason an extra one is being passed in somewhere.

Moving insertable and updatable = false to the relationship annotation breaks the cascade (I get a "personId can't be null" error)

Any idea what I'm doing wrong?

Thanks in advance,
Sean

P.S. Here's the whole stack trace:

By the way, the docs say that the @Column annotations are unnecessary on the composite primary key class. However, if I remove them, the generated query uses the field names instead of the column names, even though the column names are specified in the main class.

For example, if I remove them from the TipActionId class (leaving them in TipAction), here's the query that's generated:

Code:
/* get current state poscore.model.TipAction */ select tipaction_.personId, tipaction_.tipName, tipaction_.action_type as action3_1_, tipaction_.date as date1_, tipaction_.person_id as person5_1_ from tip_action tipaction_ where tipaction_.personId=? and tipaction_.tipName=?


Which naturally gives the error:
Code:
Unknown column 'tipaction_.personId' in 'field list'


Any idea why this is happening?

Bump - sorry, but I'm still stuck on this. Anyone have any idea?

Hello did you try to use the person id reference a part of the primary key instead of a Long property as a representation of that reference?

like this

Code:
@Entity @Table(name="tip_action") @IdClass(TipActionId.class)
public class TipAction extends AbstractModelObject {
   @Id
   @Column(name="tip_name")
   private String tipName = null;

   @Column(name="action_type")
   @Enumerated(EnumType.STRING)   
   private ActionType actionType = null;
   
   @Column(name="date")
   private Date date = null;
   
   //Removed
   //@Id
   //@Column(name="person_id", nullable=false, insertable=false,     //updatable=false)
  // private Long personId;
   
   @Id
  // @ManyToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER, optional=false)
   //@JoinColumn(name="person_id", nullable=false)
   private Person person;
....
}


You also need to change the id class to reflect the changes proposed above,

Code:
@Embeddable
public class TipActionId implements Serializable
{
  ...

  @ManyToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER, optional=false)
   @JoinColumn(name="person_id", nullable=false)
  private Person person;

  ...
}


regards,

Thanks for the response. I did try that approach. It causes an infinite loop. Apparently a cousin of this known bug in Hibernate.

I have used this approach with the xml configuration and works flawlessly...

Didn't realize there were actual function differences with the XML configuration. Makes me wonder if I should re-think going with annotations.
