Hi all,

I have a problem with calling sesion.saveOrUpdateCopy(obj)

my class is the following:

public class Collateral
{
private Long id;
private String text;

public Long getId() { return id; }
public void setId(Long id) { this.id = id; }

public String getText() { return text; }
public void setText(String text) { this.text = text; }
}

mapping is the following:

<class name="Collateral" table="collateral">
<id name="id" type="long" column="id">
<generator class="assigned"/>
</id>
<property name="text" type="string" column="text"/>
</class>

I do the following java calls:

Collateral collateral = new Collateral();
collateral.setId(new Long(5));
collateral.setText("some text");
session.saveOrUpdateCopy(collateral);

And I get the following exception:

testCompleteEnterApplication(MyTest)java.lang.NullPointerException
at net.sf.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:96)
at net.sf.hibernate.persister.AbstractEntityPersister.getPropertyValues(AbstractEntityPersister.java:246)
at net.sf.hibernate.impl.SessionImpl.doCopy(SessionImpl.java:3990)
at net.sf.hibernate.impl.SessionImpl.saveOrUpdateCopy(SessionImpl.java:3938)


Am I doing anything wrong?

thanks,
Andrey

Nothing in what you've showed. It works.

Emmanuel, thanks!

But it REALLY doesn't work.

Here is full bebug output. Could you please take a look?

Here is the method doCopy from SessionImpl class (it is called from saveOrUpdateCopy)

public Object doCopy(Object object, Serializable id, Map copiedAlready) throws HibernateException {
if (object==null) return null;

if (object instanceof HibernateProxy) {
LazyInitializer li = HibernateProxyHelper.getLazyInitializer( (HibernateProxy) object);
if ( li.isUninitialized() ) {
return load( li.getPersistentClass(), li.getIdentifier() ); //EARLY EXIT!
}
else {
object = li.getImplementation();
}
}

if ( copiedAlready.containsKey(object) ) return object; //EARLY EXIT!
EntityEntry entry = getEntry(object);
if (entry!=null && id!=null && entry.id.equals(id) ) return object; //EARLY EXIT!

copiedAlready.put(object, object);
Class clazz = object.getClass();
ClassPersister persister = getClassPersister(clazz);
if ( id==null && persister.isUnsaved(object) ) {
saveWithGeneratedIdentifier(object, Cascades.ACTION_COPY, copiedAlready);
return object; //TODO: handle its proxy (reassociate it, I suppose)
}
else {
if (id==null) id = persister.getIdentifier(object);
Object result = get(clazz, id);
if (result==null) {
saveWithGeneratedIdentifier(object, Cascades.ACTION_COPY, copiedAlready);
}
else if ( Hibernate.getClass(result)!=clazz ) {
throw new WrongClassException("class of the given object did not match class of persistent copy", id, clazz);
}
else if (
persister.isVersioned() &&
!persister.getVersionType().equals( persister.getVersion(result), persister.getVersion(object) )
) {
throw new StaleObjectStateException(clazz, id);
}

//cascade first, so that all unsaved objects get saved before we actually copy
Cascades.cascade(this, persister, object, Cascades.ACTION_COPY, Cascades.CASCADE_ON_COPY, copiedAlready);

Object target = unproxy(result);
//no need to handle the version differently
Object[] copiedValues = TypeFactory.copy(
persister.getPropertyValues(object),
persister.getPropertyValues(target),
persister.getPropertyTypes(),
this,
target
);

persister.setPropertyValues(target, copiedValues);
return result;
}
}


Please pay attention at the fact that if the object we are trying to saveOrUpdateCopy does not exists in the DB then the statement

Object result = get(clazz, id);

returns NULL. That is why

Object target = unproxy(result);

is also NULL.

And that causes NullPointerException when we call
persister.getPropertyValues(target)

Post the materials to JIRA please.
