hbm2hbmxml task generates error for @ElementCollection annotation
-----------------------------------------------------------------
Key: HBX-1177
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1177
Project: Hibernate Tools
Issue Type: Bug
Components: ant
Reporter: Grzegorz Aniol
Affected version is 3.4.0CR1.
I'm running hbm2hbmxml task from ant script to generate hibernate mapping files based
on annotations in entities.
I'm getting an error: "Expression property.cascade is undefined on line 10,
column 14 in hbm/map.hbm.ftl" for an entity which is using @ElementCollection
annotation.
====================================================================
Here is the example of a class:
====================================================================
@Entity
@Table(name = "configentry2")
public class ClassA {
@Id
@Column(name = "id")
private int id;
@ElementCollection
@MapKeyColumn(name = "key")
@Column(name = "value", columnDefinition="TEXT")
@CollectionTable(name = "configentry_map2", joinColumns = @JoinColumn(name =
"configentry_id"))
@ForeignKey(name = "fk_belongs_to_config")
private Map<String, String> entries;
}
====================================================================
Here is the full exception stack:
