Hi,
how should I map the following collection:

Code:

@CollectionOfElements
    @Type(type = "com.alcatel.rose.model.hibernate.ULDLValueIntegerType")
    @Columns(columns = {@Column(name = "ulcel"), @Column(name = "dlcel")})
    @Cascade(value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    @MapKeyManyToMany
    public Map<ChannelType, ULDLValueInteger> getCeElements()

ChannelType is annotated with @Entity and ULDLValueInteger is persisted using a hibernate UserType. When persisted, a ULDLValueInteger, it uses 2 columns in the database.

Code:

public class ULDLValueInteger {
    private Integer ul;
    private Integer dl;
 .......
}

Using the above annotations I get an exception:

Code:

Caused by: org.hibernate.MappingException: collection index mapping has wrong number of columns: com.alcatel.rose.model.NodeBType.ceElements type: com.alcatel.rose.model.hibernate.ULDLValueIntegerType
   at org.hibernate.mapping.IndexedCollection.validate(IndexedCollection.java:69)
   at org.hibernate.cfg.Configuration.validate(Configuration.java:1030)
   at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1211)
   at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:688)

Any help is highly appreciated.

It seems to work with the latest version of hibernate-annotations
hibernate-annotations-3.2.0.GA

Hi,
I'm having trouble trying to map my Map, i want the value of the map to use a UserType.

Code:

@CollectionOfElements
@JoinTable(name = "link_table", joinColumns = @JoinColumn(name = "id"))
@Type(type = "my.package.URLUserType")
@Column(name = "link_url")
@MapKey(columns = { @Column(name = "link_type") })
public Map<String, URL> getLinkMap() { ... }

The columns link_type and link_url are both VARCHAR2.

The above code causes both the key and value to be set as URL objects rather than just the value.
I need a way to specify that the value should use the URLUserType and the key should be a String.

I've tried this with both hibernate-annotations-3.2.0.GA and hibernate-annotations-3.3.0.GA.

Any help would be greatly appreciated.
