------------------------------
Seeing a similar problem here. Just upgraded to hibernate 3.2.1 GA
I have two classes like such:
@Entity
@Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class Category implements TanEntity, Imageable
{
...
@Id
private String id;
@Version
private Long version = null;
....
....
@CollectionOfElements
@OneToMany(cascade = CascadeType.ALL)
@MapKey(name = "name")
@JoinColumn
@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
private Map<String, CategoryAttribute> attributeValues = new HashMap<String, CategoryAttribute>();
....
....
}
@Entity
@Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class CategoryAttribute implements TanEntity
{
@Id
@GeneratedValue(generator = "system-uuid")
@GenericGenerator(name = "system-uuid", strategy = "uuid")
private String id;
@Version
private Long version;
private String name;
@CollectionOfElements
@org.hibernate.annotations.MapKey(columns={@Column(name="productCount")})
@Column(name="productCount", nullable=false, columnDefinition="INTEGER UNSIGNED")
private Map<String, Integer> values = new HashMap<String, Integer>();
....
....
}
Both classes are mapped in the hibernate.cfg.xml file like such:
....
....
<mapping class="com.ac.tan.core.beans.CategoryAttribute"/>
<mapping class="com.ac.tan.core.beans.Category"/>
....
When I deploy my web application, I see the following trace in my tomcat logs:
1534 ERROR org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/t] listenerStart [3696] - Exception sending context initialized event to listener instance of class com.ac.tan.web.TanContextListener

> Using an OneToMany/ManyToMany relationship to hbm mapped class from an annotated class causes error. If both classes are mapped the same way (annotated or hbm) this works fine. Also using a ManyToOne or OneToOne relationship works correctly.
