I am using hibernate annotations with @Embedded objects. Things work fine if I do a Hibernate.initialize(my.getEmbeddedObject()) ,but if I don't do an explicit initilize on my embedded object, I get a
org.hibernate.PropertyValueException
not-null property references a null or transient value: com.reffects.dmi.dbom.PlaylistAttraction.nameDescription.name

Is there a way I can annotate the class so that this Embedded property is eagerly loaded when the class is loaded?

Thanks very much. I guess for now I am going to nuke my Embedded objects and just switch back to simple properties for now, but was wondering why this functions this way.



Hibernate version:
hibernate-3.2.0.cr1.jar
hibernate-annotations-3.1beta9.jar

Mapping documents:
@Embedded
public NameDescription getNameDescription() {
return nameDescription;
}
public void setNameDescription(NameDescription nameDescription) {
this.nameDescription = nameDescription;
}
private NameDescription nameDescription = new NameDescription();

Code between sessionFactory.openSession() and session.close():
//spring...

Full stack trace of any exception that occurs:
org.springframework.orm.hibernate3.HibernateSystemException
not-null property references a null or transient value: com.reffects.dmi.dbom.PlaylistAttraction.nameDescription.name; nested exception is org.hibernate.PropertyValueException: not-null property references a null or transient value: com.reffects.dmi.dbom.PlaylistAttraction.nameDescription.name

this is kind of related to http://jira.jboss.com/jira/browse/HIBERNATE-50

I added a simple property to my EmbeddedObject, now everything is fine.


Summary:
If you use any EmbeddedObjects, include at least one simple property (int, boolean), if you have only string properties, you will have to explicitely initialize the object.

it s not related to String, it's related to the fact that an object having null properties is set to null.
