Why is hibernate generating Update to the child tables, where i have a one-to-many problem?

I have create an addRules method to add the rules to the parent ...

Also I have the cascade="all" and inverse="true"

Hibernate version:
hibernate 3.0.5
Mapping documents:
<class name="model.Menu" table="menu_level" >
<id name="levelId" type="integer" unsaved-value="0">
<column name="LEVEL_ID" sql-type="number(10)" not-null="true" />
<generator class="assigned"/>
</id>

<property name="name" type="string">
<column name="NAME" length="6" not-null="true" />
</property>
<bag name="rules" cascade="all" inverse="true" lazy="false" >
<key column="PARENT_LEVEL_ID"/>

<one-to-many class="model.Rule" />

</bag>
</class>




<class name="model.Rule" table="ice_rule" >
<id
column="rule_id"
type="integer"
name="ruleId" unsaved-value="0">
<generator
class="assigned">
</generator>
</id>
<property
name="reasonId"
column="REASON_ID" />
<property
name="ruleTypeId"
column="RULE_TYPE_ID" />

<many-to-one name="menu" class="model.Menu" column="parent_level_id" insert="true" update="true">
</many-to-one>

</class>

Code between sessionFactory.openSession() and session.close():
Menu m = new Menu();
m.setLevelId=(99999);
m.setName=("test");
Rule r = new Rule();

r.setRuleId(9999);
r.setRuleTypeId(0);
r.setReasonId(0);

m.addRule(r);
dao.save(m);

unsaved value to any and the thing works :-D
