.betwix file assigned to a JDK class

[Marcos Hass W]

Hi all,

I have a class that extends
java.beans.beancontext.BeanContextChildSupportits name is
AbstractBean, below a snippet.:


/** <tt>JavaBean</tt> base responsável pelos mecanismos de notificação de
alteração
* de propriedades e clonagem. A extensão a partir de
<tt>BeanContextChildSupport</tt>
* permite que o bean seja posicionado dentro de um <tt>BeanContext</tt> e
esteja
* apto a questionar propriedades existentes em outros beans presentes
também no
* contexto.

public abstract class AbstractBean extends BeanContextChildSupport
       implements Cloneable, Comparable, Serializable {

   /** Delegate <tt>PropertyChangeSupport</tt> responsável pela notificação
dos
    * listeners atentos às alterações nas propriedades do
<tt>javabean</tt>.
    *
    * @see <a href="
http://java.sun.com/docs/books/tutorial/javabeans/properties/bound.html";>
    *
http://java.sun.com/docs/books/tutorial/javabeans/properties/bound.html</a>
    */
   protected transient PropertyChangeSupport changes = new
PropertyChangeSupport(this);

   /** Delegate a <tt>VetoableChangeSupport</tt> responsável pela
notificação
    * dos <tt>VetoableChangeListeners</tt> que irão escutar os valores
alterados
    * e irão <tt>vetar</tt> ou não a alteração.
    */
   protected transient VetoableChangeSupport vetoable = new
VetoableChangeSupport(this);

   /** Constructor de <code>AbstractBean</code>.*/
   public AbstractBean() {
       super();

       beanContextChildPeer = this;

       pcSupport = new PropertyChangeSupport(beanContextChildPeer);
       vcSupport = new VetoableChangeSupport(beanContextChildPeer);
   }

   public AbstractBean(BeanContextChild bcc) {
       super();

       beanContextChildPeer = (bcc != null) ? bcc : this;

       pcSupport = new PropertyChangeSupport(beanContextChildPeer);
       vcSupport = new VetoableChangeSupport(beanContextChildPeer);
   }

//...

}

I have several bean classes that extend AbstractBean and any time I try to
submit these extended classes to BeanWriter I get a CyclicReferenceException
.
I've discovered that BeanContextChildSupport has some fields that produce
this cyclic problem and for this reason I've associated a
AbstractBean.betwixt file to the AbstractBean class as follows:

<?xml version='1.0' encoding='UTF-8' ?>
<info primitiveTypes='attribute'>

   <element name='abstractbean'>
       <hide property='beanContext'/>
       <hide property='beanContextChildPeer'/>
       <hide property='pcSupport'/>
       <hide property='rejectedSetBCOnce'/>
       <hide property='vcSupport'/>
       <hide property='changes'/>
       <hide property='vetoable'/>
       <addDefaults/>

   </element>

</info>

The problem is that I'm still getting the cyclic problem ;-(
Does someone know what's wrong ?
How do I associate a .betwixt file with the
java.beans.beancontext.BeanContextChildSupport class ?

Thank you very much
Marcos
