[Hibernate-JIRA] Created: (HHH-3836) composite-element with null columns in map is ignored

composite-element with null columns in map is ignored
-----------------------------------------------------
Key: HHH-3836
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3836
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.0.SP1
Environment: 3.3.0 SP1, noticed with Oracle and H2 but probably happens with all databases
Reporter: Benoit Goudreault-Emond
Attachments: patate.zip
When a composite element with all properties set to NULL is inserted in a map of the said composite element, the data gets inserted to the database but is never retreived when reloading the entity.
For instance, with an entity
@Entity
public class TestEntity {
@Id
private int id;
@CollectionOfElements
private Map<String, AccessPeriod> roleAccesses = new HashMap<String, AccessPeriod>();
// boilerplate getters/setters/etc omitted
}
And AccessPeriod being
@Embeddable
public class AccessPeriod {
public Date startDate;
public Date endDate;
}
If you insert in the map an AccessPeriod with both startDate and endDate set to null and persist the TestEntity,
an entry is inserted in the auxiliary table, but when getting the TestEntity back, the map is empty.
You get the same problem with a mapping file.
This used to work in Hibernate 2.1--I found this out while porting some code to 3.3.
See the attached example. You'll need to include Hibernate and h2 (com.h2database:h2 1.0.20061217) on your classpath to run it with the given jdbc.properties, but feel free to change it.

When I activate the result set wapper, hibernate.jdbc.wrap_result_sets=true, I can have a stacktrace such as :

I think that columnNameToIndexCache map should be synchronized.
I got the exception with 3.2.7 but I had a look at the latest version and the bug is still there.
