Hi its me again :-)

I am a bit confused... I dont get my Many-to-One Mappings work probably.

The case is: Class Order is containing an association to OrderDetails.

now if i try to save the Order with an unsafed OrderDetail i get an exception.

e.g.:

Order ord = new Order...

OrderDetails detail = new OrderDetails...

ord.Details = detail;

session.Save(ord);

...

If i save OrderDetails before, ist working fine. So might there be something wrong in my mapping or is it intend to work like this?

Thx again,

Chris

Sry forgot to write down the code...
Here it comes:

public class Kunde
{
private string name;
private string vorname;
private int kundenNr;
private Adresse adresse;
...
}

Kunde.hbm.xml:

<class name="NHTest.Kunde, NHTest" table="Kunde">
<id name="KundenNr" column="KundenNr" type="Int32">
<generator class="assigned" />
</id>
<property name="Name" column= "Name" type="String" length="40"/>
<property name="Vorname" type="String" length="20"/>
<many-to-one
name="Adresse"
column="Id"
cascade="all"
not-null="false"/>
</class>



public class Adresse
{
private int id;
private string strasse;
private int plz;
private string stadt;
...
}

Adresse.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="NHTest.Adresse, NHTest" table="Adresse">
<id name="Id" column="Id" type="Int32">
<generator class="assigned" />
</id>
<property name="Strasse" column= "Strasse" type="String" length="40"/>
<property name="PLZ" column="PLZ" type="Int32"/>
<property name="Stadt" type="String" length="10"/>
</class>

</hibernate-mapping>

what am i doing wrong?

Thx anyway

Chris

Eh... first you speak of order and order details, and then you show customers and addresses instead :)

Your problem is that you use assigned identifiers. Cascades (aka persistence by reachability) won't work correctly with them.

Hi thx for this hint!

Yeah i realized to late my mistake :-) I was to tired.

I wil check this out!
