As described in the documentation, you must use unsaved-value="0" for a primitive id type.
The User Forum is the correct place for these kinds of issues.

Key: HB-133
Summary: Cascading a many-to-one child object in MYSQL
Type: Bug
Status: Closed
Priority: Major
Resolution: REJECTED
Project: Hibernate2
Components:
core
Versions:
2.0 final
Assignee: Gavin King
Reporter: Todd Nine

Environment: Orion Application Server
MY SQL DB
Java 1.4.1_02
Description:
This is a concrete example of the Cascades.isUnsaved(Serializable id) error.
We have 2 class Customer and Address, Address is a child of Customer.
if we have the following in the Customer.hbm.xml file:
<many-to-one name="address" class="com.sigma.webtools.modal.services.facades.facadechildren.Address" cascade="all"/>
and Address.hbm.xml is the following
<hibernate-mapping>
<class name="com.sigma.webtools.modal.services.facades.facadechildren.Address" table="WTS_ADDRESS">
<id name="id" type="long">
<generator class="native"/>
</id>
<property name="firstName" type="string"/>
<property name="lastName" type="string"/>
<property name="address1" type="string"/>
<property name="address2" type="string"/>
<property name="address3" type="string"/>
<property name="city" type="string"/>
<property name="state" type="string"/>
<property name="zip" type="string"/>
<property name="contact" type="string"/>
<property name="deliveryType" type="string"/>
<property name="addressType" type="string"/>
</class>
</hibernate-mapping>
when the generator is "native" and the variable type is a primitive numberic, the following will return 0;
//line 1210 in file net.sf.hibernate.impl.SessionImpl
Serializable id = persister.getIdentifier(object);
Therefore, when the following is called
if ( persister.isUnsaved(id))
The following evaluates false
return id==null;
The child object will not be saved because an update is called instead of a save.
