"generated-class" Metatag with Composite ID Omits

I'm trying to use the generate-class metatag to generate base classes for persistence, as per:
http://www.onjava.com/pub/a/onjava/2005/12/14/hibernate-class-generation-with-hbm2java.html?page=last

I am using Hibernate 3.1.3CIP with Hibernate Tools 3.1. What I notice is that for any class that contains a composite-id, I don't see generated properties other than those contained in the composite-id itself. For example, this:

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
   <class mutable="true" name="Test" table="test">
      <meta attribute="generated-class">TestBase</meta>
      <composite-id name="id" class="com.bgi.ips.identifier.composite.TestId">
         <meta attribute="use-in-equals">true</meta>
         <key-property name="issueId" column="issue_id" type="integer" />
         <key-property name="issueCodeType" column="issue_cd_type" type="string" />
      </composite-id>
      <property name="code" type="string">
         <column name="issue_cd" />
      </property>
   </class>
</hibernate-mapping>

produces this:

public class TestBase implements java.io.Serializable {

Code:

    // Fields    

     private Integer issueId;
     private String issueCodeType;

     // Constructors

    /** default constructor */
    public TestBase() {
    }
...

(Notice the missing "code" property.)

This problem seems to be universal for me. As soon as I replace the <composite-id> with a normal <id> tag, it generates all the properties. I have no idea why this would be the case. Is this a bug, or am I doing something wrong?
