Sorry, here it is
I am using appfuse 2 with Hibernate implementation.
I have a table with this definition
CREATE TABLE /*!32312 IF NOT EXISTS*/ `catalog`
( `id` bigint(20) NOT NULL auto_increment,
`catalog_name` varchar(100) NOT NULL,
`active` varchar(1) NOT NULL,
`date_created` datetime default NULL,
PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
I would like to set defaults for active and date_created columns.
So in my Catalog POJO, I declared
@PrePersist
public void setDefaults() {
//All new catalog records should be active.
if (getActive() == null ) {
setActive("Y");
}
if (getDateCreated() == null) {
setDateCreated(new Date());
}
}
When I attempt to save, I get this error
Caused by: org.springframework.dao.DataIntegrityViolationException: not-null
property references a null or transient value:
com.sonycard.cast.model.Catalog.acti
ve; nested exception is org.hibernate.PropertyValueException: not-null
property references a null or transient value:

org.appfuse.service.impl.GenericManagerImpl.save(GenericManagerImpl.java:64)
I then moved my @PrePersist method into a model listener class and annotated
my POJO with it.
@EntityListeners({com.sonycard.cast.model.listener.CatalogModelListener.class})
I still get the same error. Anyone know how to set defaults for entity
fields?
Would one solution be to write a custom manager (like PersonManager in the
tutorial) and override the save() method?.
Thanks
Franco
