Mapping ID of parent as a property within a component

Given the mapping:

Code:

<class name="Foo" table="foos">
    <id name="id" type="long" unsaved-value="0">
        <generator class="native"/>
    </id>

    <component name="fooInfo" class="FooInfo" >
        <property name="name" type="string"/>
    </component>
</class>

How can FooInfo contain the 'id' property of Foo ?

Check the <parent> tag

So I should be using:

Code:

<class name="Foo" table="foos"> 
    <id name="id" type="long" unsaved-value="0"> 
        <generator class="native"/> 
    </id> 

    <component name="fooInfo" class="FooInfo" > 
        <parent name="id"/>
        <property name="name" type="string"/> 
    </component> 
</class> 

Hibernate's codegenerator doesn't output a accessor method for 'id' in my sourcefile, any ideas?

No parent give you a callback to Foo object.
If you only want id, then a property mapped in the same column with insert and update to false would do the job.

parent is a 2.1 feature, maybe the codegenerator isn't uptodate.

I ran into this problem as well, using the Hibernate 2.1.2 and Hibernate Extensions 2.0.2. I didn't see any reference to this in the JIRA, shoud I add it, or is this fixed in CVS...?
