I have a object1 which have an other object2 who attribute, and in the base I want to save with the object1 the idkey to the other object2.

the configured hibernate object1 is:

<hibernate-mapping>
<class name="Object1" table="Object1">
<id column="name" name="name" unsaved-value="0">
<generator class="native"/>
</id>
<property column="disable" name="disable"/>
..
<property column="xxx" name="xxx"/>
<one-to-one name="Object2Id" class="Object2" foreign-key="idObject2" cascade="all"/>
</class>
</hibernate-mapping>

and the object2 is:

<hibernate-mapping>
<class name="Object2" table="Object2">
<id column="idObject2" name="idObject2" unsaved-value="0">
<generator class="native"/>
</id>
<property column="name" name="name"/>
</class>
</hibernate-mapping>


I want that when I save the object1, save the object2 too, and put in the attribute Object2Id the key to the table Object2

but, when I do that, hibernate first do, save Object1 and a update Object2 and this throws exception because the Object2 doesn`t exist yet.
I want that do a save Object2, not a update!

Who can I do this?? What is wrong?
Thanks.
