Just to verify this, I added following two properties to
org.apache.openjpa.persistence.fields.EnumFieldType
private Date createdOn;
private boolean active = true;
And modified TestEnumQueryConstructor :
setup() {
if (emf instanceof OpenJPAEntityManagerFactory) {
((OpenJPAEntityManagerFactory) emf).addLifecycleListener(new
EntityLifecycleHandler(), (Class[]) null);
}
....
}
public void testEnumQueryConstructor() {
..
assertEquals(SampleEnum.BAR, e.getEnumField());
assertNotNull(e.getCreatedOn());
assertFalse(e.isActive());
}
public class EntityLifecycleHandler extends AbstractLifecycleListener {
@Override
protected void eventOccurred(LifecycleEvent event) {
switch (event.getType()) {
case LifecycleEvent.BEFORE_PERSIST:
if(event.getSource() instanceof EnumFieldType) {
EnumFieldType e = (EnumFieldType)event.getSource();
e.setCreatedOn(new Date());
e.setActive(false);
e.setEnumField(SampleEnum.BAR);
}
break;
default:
break;
}
}
}
Both of these fail:
assertNotNull(e.getCreatedOn());
assertFalse(e.isActive());
But assertEquals(SampleEnum.BAR, e.getEnumField()); passes the test!
Sorry for not giving a full test case as I'm not very familiar with it! Hope
this helps.

Hi,
I've a mapped super class 'BaseEntity' that has common properties like
Date createdOn; Date updatedOn; boolean active; Company company; User
createdBy; etc.
Initially I used @EntityListeners defined at the BaseEntity and in
LifeCycleEvent handler on PrePersist(), I update these above common
properties.
I wanted my own instance of the listener(or to get hold of it), as I've to
update these from the UI module. But I couldn't find a way to do this in JPA
as it accepts only classes. Thanks to OpenJPA, I could achieve this easily
like this:
if (entityManagerFactory instanceof OpenJPAEntityManagerFactory) {
((OpenJPAEntityManagerFactory)
entityManagerFactory).addLifecycleListener(entityLifecycleHandler, (Class[])
null);
}
But in both the above cases, inside prePersist method, If I set the
properties of type Date or Boolean, they do not get saved.
Other properties like Company, User, etc. are saved properly.
Are the entities passed can not be modified in the listener? Or Is there
any other approach that could achieve this?
Thanks and Regards,
Prashant
