Hi,
I have this exception
org.hibernate.ObjectDeletedException: deleted object would be re-saved
by cascade (remove deleted object from associations): [InstrumentDomain#918]
But am not doing any deletions?
I have this code
public BondResult getBondResultRows(Integer[] ids) {
BondResult result = new BondResult();
if(!(ids!=null && ids.length>0))
return result;
// open transaction
Session session = HibernateUtil.getCurrentSession();
Transaction tx = session.beginTransaction();
try
{
// construct search
String queryString = "select inst from InstrumentDomain inst" +
" left join fetch inst.instrumentIdentifier ident" +
" inner join ident.schemeInfo info" +
" inner join inst.instrumentType as type" +
" left join fetch inst.debtIssueData did" +
" left join fetch did.interestRate intr" +
" left join fetch did.denomination denom" +
" left join fetch inst.issuerClass issr" +
" left join fetch issr.location loc" +
" left join fetch intr.indicatorsType indtype" +
" where inst.id in (:ids)";
// build query
Query query = session.createQuery(queryString);
query.setParameterList("ids", ids);
// then create a BondResult with the constituent objects
try {
List<InstrumentDomain> results = query.list();
if (results != null)
{
for (InstrumentDomain instrument : results)
{
BondResultRow brr = new BondResultRow(instrument);
result.addBondResultRow(brr);
}
}
} catch (ClassCastException cce) {
Log.error("Hibernate cast error: ", cce);
}
// commit transaction
tx.commit();
}
catch (RuntimeException e)
{
tx.rollback();
throw e;
}
// done
return result;
}
Which calls this
public BondResultRow(final InstrumentDomain domain)
which is quite long, but definitely does not delete anything.
So I am at a loss to explain why I get this exception.
Here are my PersistanceOptions
props.setProperty(PersistenceOptions.MAXIMUM_SQL_NAME_LENGTH , "28");
props.setProperty(PersistenceOptions.ID_FEATURE_AS_PRIMARY_K EY, "true");
props.setProperty(PersistenceOptions.DEFAULT_ID_FEATURE_NAME , "id");
props.setProperty(PersistenceOptions.JOIN_COLUMN_NAMING_STRA TEGY, "simple");
props.setProperty(PersistenceOptions.JOIN_TABLE_FOR_NON_CONT AINED_ASSOCIATIONS,
"false");
props.setProperty(PersistenceOptions.ALSO_MAP_AS_CLASS, "false");
props.setProperty(PersistenceOptions.DEFAULT_TEMPORAL_VALUE, "DATE");
props.setProperty(PersistenceOptions.DISABLE_ECONTAINER_MAPP ING, "true");
props.setProperty(PersistenceOptions.ALWAYS_VERSION, "false");
props.setProperty(PersistenceOptions.ALWAYS_MAP_LIST_AS_BAG, "true");
props.setProperty(PersistenceOptions.INHERITANCE_MAPPING, "JOINED");
//ManyToOne and OneToMany are normally fetch eagerly, only if you do
SET_PROXY=true then these are set to lazy
props.setProperty(PersistenceOptions.SET_PROXY, "true");
Any ideas?
Thx
David

Hi David,
The main reason why this can happen is when an child is removed from its containment relation to the
parent. Then because of orphan-delete the object will automatically be deleted.
One thing you can do to analyse the situation is to use a Hibernate Interceptor. The interceptor has
an ondelete method where you can set a breakpoint to see what causes the delete action. You need to
extend the EMFInterceptor and then set your Interceptor class in Teneo like this:
final ExtensionManager extensionManager = dataStore.getExtensionManager();
extensionManager.registerExtension(EMFInterceptor.class.getN ame(), DavidsInterceptor.class.getName());
and then initialize the datastore.
An interceptor can also be used to analyse why hibernate updates an object. At least that is what I
use it for.
