 Post subject: Seltsames Verhalten bei selbst erzeugter ID

Hallo!

Ich habe hier gerade ein setsames Problem: Wenn ich folgendes xml zum Erzeugen eine hibernate-objektes (und der DB und der files....) verwende, so klappt das wunderbar, und wenn ich auf einem derart erzeugten objekt session.save(obj) aufrufe, so wandert das Objekt mit der gesammten Substruktur brav in die DB.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping auto-import="false" default-cascade="all-delete-orphan" default-lazy="false">
<class name="de.my.Product" table="Product">
<id name="Hjid" type="org.hibernate.type.LongType">
<generator class="native"/>
</id>
<discriminator type="org.hibernate.type.StringType">
<column name="Hjtype"/>
</discriminator>
....

Verwende ich hingegen einen von mir selbst erzeugten Primärschlüssel, so klappt das auch erst mal ganz prima, und ich kann das objekt auch speichern, allerdings wird nur die Substruktur gespeichert, der Eintrag für das Produkt selber fehlt in der DB, will sagen keine Zeile in der Product Tabelle:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping auto-import="false" default-cascade="all-delete-orphan" default-lazy="false">
<class name="de.my.Product" table="Product">
<id name="DigitalIcpn" type="org.hibernate.type.StringType">
<generator class="assigned"/>
</id>
<discriminator type="org.hibernate.type.StringType">
<column name="Hjtype"/>
</discriminator>
....

Hat hier irgendwer eine Idee, was ich übersehe? Ich studier schon eine Zeit lang die Doku, habe aber noch nichts wirklich brauchbares dazu gefunden.

Auch Hinweise was man mal probieren könnte sind herzlich willkommen.

Grüßle und danke schon mal im Voraus

Ok, der ist wirklich ehr übersichtlich:

Ich pumpe das Produkt aus einem xml file hoch in den Speicher, und save es:

private void handleProduct(File xml){
ProductData data = (ProductData) unmarshaller.unmarshal(getSource(xml));
Product xmlProduct = (Product)data.getProduct().iterator().next();
Session session = hibernateTemplate.getSessionFactory().openSession();
session.save(xmlProduct);
result.addInfoMessage("Imported: "+xmlProduct.getDigitalIcpn());
}

Und Du bist wirklich sicher, dass im XML ne id steht? Ich glaub da brauch ich ein debug log um da was sagen zu können ;-)

Leider bin ich mir da sicher, denn wenn ich hibernate die ID generiren lasse, ist das feld, welches ich gerne als ID hätte, nachher gefüllt.
Hier ist mal, was ich im Log finde, wenn ich hibernate seine ID verwenden lasse (er kommt da gerade vom verewigen der substruktur wieder, wenn du davor noch was brauchst, einfach melden):

Code:
...

DEBUG QueueWorker org.hibernate.engine.Cascades - done processing cascade ACTION_SAVE_UPDATE for: de.arvato.repository.emi.impl.ProductImpl


Und so sieht es aus, wenn ich die DigitalIcpn als id verwenden möchte (die ist gefüllt, siehe parameter 20 oben)

Code:
...
DEBUG QueueWorker org.hibernate.event.def.DefaultSaveOrUpdateEventListener - saving transient instance
DEBUG QueueWorker org.hibernate.event.def.AbstractSaveEventListener - generated identifier: 0094634227452, using strategy: org.hibernate.id.Assigned

...
