Benoit commented on ANN-450:
----------------------------
Hello,
I can report the same error even within a JAVA SE environment. The @MapKey doesn't
seem to work if the mapKey is an Embeddable field. I would really like to see this issue
fixed, thank you !
I tried to enter into Hibernate's code, through the Eclipse debugger, and it seems
that the SimpleSelect.addColumns function receives as a first argument an array of columns
with the good names (ie. the two default ones for the embedded key if it has 2 fields, or
the ones overrided) but the second array only contains 1 column name "ID1_" . I
hope this helps...
@MapKey does not work with embedded fields
------------------------------------------
Key: ANN-450
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-450
Project: Hibernate Annotations
Type: Bug
Versions: 3.2.0.cr3
Environment: Windows, JBoss Embedded EJB3 with the latested Hibernate Libaries (manually
replaced)
Reporter: Bryan Brouckaert
Attachments: TestCase.zip
@javax.persistence.MapKey does not seem to work with @embedded fields.
The following is programmed (simplified):
@Entity
public class MyClass
{
@Id
@GeneratedValue
private int id;
@MapKey(name="myKey")
private Map<KeyClass, OtherClass> myField;
...
}
@Entity
public class OtherClass
{
@Id
@GeneratedValue
private int id;
@Embedded
private KeyClass myKey;
...
}
@Embeddable
public class KeyClass
{
private String key1;
private String key2;
}
The following exception is thrown:
ERROR 11-10 08:52:30,862 (AbstractController.java:incrementState:440) -Error installing
