[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6811) java.lang.ClassCastException when using @JoinColumnsOrFormulas
java.lang.ClassCastException when using @JoinColumnsOrFormulas
---------------------------------------------------------------
Key: HHH-6811
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6811
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.6.8
Environment: Ubuntu Linux, Oracle 11G DB
Reporter: Vladimir Tsichevski
The following declaration:
@Entity
@Table(name = "SOMETABLE")
public class Process {
@Id
@Column(name = "ID", length = 19, nullable = false)
long id;
@ManyToOne
@JoinColumnsOrFormulas({
@JoinColumnOrFormula(formula=@JoinFormula(value="PARENTID")) })
@Fetch(FetchMode.JOIN)
Process parent;
}
causes the following exception:
java.lang.ClassCastException: org.hibernate.mapping.Formula cannot be cast to
org.hibernate.mapping.Column

...
Note: if I just use:
@ManyToOne @JoinColumn(name = "PARENTID")
everything works well.
