one-to-one mapping is not updated when parent is saved

I have an object "Contract" that has a one-to-one mapping with an "Property". When I create a new Contract and save it, the Property object is also saved and persisted to the database.

However, when I update the Contract and Property objects and attempt to persist, the Contract object is updated, however the modified Property object is not updated.

I checked the SQL output, and there is an update entry for the Contract object.

TIA

Hibernate version:
2.1.6

Mapping documents:

Code:

  <class name="com.acme.Contract" >
    <meta attribute="class-description">
      Contract Rule Value
    </meta>

    <id name="id" type="integer">
      <meta attribute="scope-set">protected</meta>
      <generator class="native"/>
    </id>

    <one-to-one name="insuredProperty" class="com.acme.Property" cascade="save-update"/>
...

Code:

  <class name="com.acme.Property" >
    <meta attribute="class-description">
      Contract Property
    </meta>

    <id name="id" type="integer">
        <generator class="foreign">
            <param name="property">contract</param>
        </generator>
    </id>
   
    <one-to-one name="contract" class="com.acme.Contract" constrained="true"/>

why don't show your source code?

I was going to, but I wanted to just make sure that the mappings were correct, because if the mappings are correct then I should be able to figure out the source.

Anyways, I figured out was wrong, I was using Hibernate.lock() instead of Hibernate.update().

Thanks.
