@AttributeOverride of column type or name results in PropertyNotFoundException
------------------------------------------------------------------------------
Key: HHH-2946
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2946
Project: Hibernate3
Issue Type: Bug
Environment: Hibernate 3.2.5.ga, Annotations 3.3.0.ga, Spring 2.0.7, MySQL 5.0.41-community-nt, Windows Vista
Reporter: Juan Antonio Agudo
Attachments: hibernateErrorTest.zip
When trying to map a java.util.Map<String,String> hibernate by default creates VARCHAR(256) fields. When an attempt to alter for e.g. the column type to "TEXT" an Exception is thrown. For example:
@CollectionOfElements
@AttributeOverride(name="element.value", column=@Column(columnDefinition="TEXT"))
public Map<String, String> getSettings() {
return settings;
}
results in
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [C:\Users\tag\workspace\xyz\conf\applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property bytes in class java.lang.String

dynamic-map entity mode mappings with relationships rise lazy initialization during performing query

(copied from http://jira.jboss.com/jira/browse/HIBERNATE-51)
(attached IntelliJ project with test case that reproduce this issue)
If I create bidirectional relationship between two dynamic-map entities, commit a transaction and start new session, performing a query to obtain an entity raise LazyInitializationException.
(full intellij project attached)
code and mappings:
public void testSF() throws Exception
{
sf.openSession();
Session es = sf.getCurrentSession();
Transaction tx = es.beginTransaction();
Map lolo = new HashMap();
lolo.put("userName", "lolo");
es.save("PortalUser", lolo);
Map dummy = new HashMap();
dummy.put("name", "dummy");
es.save("PortalRole", dummy);
Set roles = new HashSet();
roles.add(dummy);
lolo.put("roles",roles);
Map props = new HashMap();
props.put("theme", "pp");
props.put("signature", "alalala");
lolo.put("dynamic", props);
es.save("PortalUser", lolo);
tx.commit();
sf.openSession();
es = sf.getCurrentSession();
tx = es.beginTransaction();
Query query = es.createQuery("from PortalUser where userName=:userName");
query.setParameter("userName", "lolo");
//LazyInitializationException on this LINE!!!
lolo = (Map)query.uniqueResult();
assertNotNull(lolo.get("roles"));
assertNotNull(lolo.get("dynamic"));
tx.commit();
}

also note that commenting out this 3 lines makes it work:
Set roles = new HashSet();
roles.add(dummy);
lolo.put("roles",roles);
So I guess it's about resolving roles relationship during obtaing a user object

[Hibernate-JIRA] Created: (HBX-910) hbm2ddl doesn't create identity column with custom identifier generator
by Luca Dall'Olio (JIRA)
hbm2ddl doesn't create identity column with custom identifier generator
-----------------------------------------------------------------------
Key: HBX-910
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-910
Project: Hibernate Tools
Type: Bug
Environment: hibernate 3.2.1 hsqldb 8.0.1
Reporter: Luca Dall'Olio
Priority: Minor
When defining a custom identifiergenerator which implements org.hibernate.id.PostInsertIdentifierGenerator ,
hbm2ddl doesn't define the primary key column as identity (i.e. hibernate.hbm2ddl.auto=create)
By looking at the source code, the hbm2dll depends on org.hibernate.mapping.SimpleValue.isIdentityColumn() function, which in turn has a direct dependency on IdentityGenerator.class :
public boolean isIdentityColumn(Dialect dialect) {
return IdentifierGeneratorFactory.getIdentifierGeneratorClass(identifierGeneratorStrategy, dialect)
.equals(IdentityGenerator.class);
}
in my opinion, it should depend instead on the PostInsertIdentifierGenerator interface :
public boolean isIdentityColumn(Dialect dialect) {
return IdentifierGeneratorFactory.getIdentifierGeneratorClass(identifierGeneratorStrategy, dialect)
.isInstance(PostInsertIdentifierGenerator.class);
}
Here is an example of a custom IdentityGenerator which can reproduce this problem :
package sample;
...
public class CustomIdentifierGenerator implements IdentifierGenerator, PostInsertIdentifierGenerator {
private static IdentityGenerator hibernateGeneratorDelegate = null;
public Serializable generate(SessionImplementor session, Object object)
throws HibernateException {
return hibernateGeneratorDelegate.generate(session, object);
}
public InsertGeneratedIdentifierDelegate getInsertGeneratedIdentifierDelegate(
PostInsertIdentityPersister persister, Dialect dialect,
boolean isUseGet) throws HibernateException {
return hibernateGeneratorDelegate.getInsertGeneratedIdentifierDelegate(persister, dialect, isUseGet);
}
}
Here an example mapping fragment :
<id name="id" type="long" column="DMM_ID">
<generator
class="sample.CustomIdentifierGenerator " />
</id>
