Hibernate Search on Composite Ids

Hi,

I have the following model:

Code:

@Entity
@IdClass(PersonId.class)
@Indexed(index="indexes/person")
public class Person implements Serializable {
    
    private long organizationId;
    private long personId;
    private String name;
    
    @Id
    public long getOrganizationId() {
        return organizationId;
    }
    
    public void setOrganizationId(long organizationId) {
        this.organizationId = organizationId;
    }
    
    @Id
    public long getPersonId() {
        return personId;
    }
    
    public void setPersonId(long personId) {
        this.personId = personId;
    }
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
}

@Embeddable
public class PersonId implements Serializable {
    
    private long organizationId;
    private long personId;
    
    public long getOrganizationId() {
        return organizationId;
    }
    
    public void setOrganizationId(long organizationId) {
        this.organizationId = organizationId;
    }
    
    public long getPersonId() {
        return personId;
    }
    
    public void setPersonId(long personId) {
        this.personId = personId;
    }
    
    // override equals/hashCode
}

When I do the search, I get the following error:

Code:

Caused by: java.lang.NumberFormatException: For input string: "com.test.entity.PersonId@e79f7c35"
   at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)

   at com.test.search.impl.SearchProviderImpl.searchPersons(SearchProviderImpl.java:52)
   ... 28 more

I'm I doing something wrong with the mappings?

Thanks,

Pavel

Today, Hibernate Search does not support IdClass mappings.
It supports @EmbeddedId but you need to write a custom field bridge.

November 2007 has gone. we have July 2009 now.
Does Hibernate Search support IdClass mappings today?

#edit
Okay, I have challenged my complicated Composite Key with the TwoWayFieldBridge. My class to index still uses @IdClass. :)

If someone comes with a nice solution, we can add it to the codebase, but I tend to like the custom bridge approach.
