I have a test on "optimistic-lock" attribute with component's property and found that it affects the version to be updated even though I set it to "false".
Anyone could tell the reason?

Thanks for your help.

Hibernate version: 1.2.1.4000

Mapping documents:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Model" assembly="Model">
<class name="Person" table="Person" dynamic-update="true" >
<id name="Id" column="ID" type="Int32">
<generator class="native" />
</id>
<timestamp name="Version" column="Version" />
<property name="Name" type="String" length="20" not-null="false" optimistic-lock="false" />

<component name="Info" class="Info">
<property name="Age" column="Age" type="Int32" not-null="false" optimistic-lock="false" />
<property name="Address" column="Address" type="String" length="50" not-null="false" optimistic-lock="false" />
</component>
</class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
Console.WriteLine("//save");
Person person = new Person();
person.Name = "personA";
person.Info.Age = 21;
person.Info.Address = "Home";
_session.Save(person);
_session.Flush();

System.Threading.Thread.Sleep(2000);

Console.WriteLine("//update");
person.Info.Age = 23;
_session.Flush();

Console.WriteLine("//delete");
_session.Delete(person);
_session.Flush();
