First of, it's handy to add a convenience method to your "page" component to define this "list" of objects:


  protected void addObjectToPathComponents(Object anObject, String aPageName, Object aTitle) {

  if ( anObject != null ) {
    Map  aMap = new HashMap();

    aMap.put( Path.ObjectKey, anObject );
    aMap.put( Path.PageNameKey, aPageName );
    aMap.put( Path.TitleKey, aTitle );

    this.pathComponents().add( aMap );

    return;
   }

  throw new IllegalArgumentException ( "Page.addObjectWithPageNameAndTitleToPath: null object.");
 }

Now, in each concrete page you could initialize the path components:


protected void initPathComponents()
 {
  Envelope  anEnvelope = this.value();
  Date    aDate = anEnvelope.creationDate();
  List    aList = anEnvelope.list();

  this.addObjectToPathComponents( aDate, "Timeline", "TIMELINE" );
  this.addObjectToPathComponents( aDate );

  if ( aList != null )
   {
    this.addObjectToPathComponents( aList );
   }

  this.addObjectToPathComponents( anEnvelope );
 }

Finally, the path component itself could look like this:

  <webobject name = "IsMain">
   <webobject name = "MainLink"><webobject name = "MainLabel"></webobject></webobject>
 </webobject>

 <webobject name = "IsNotMain">
   <webobject name = "Components">
     <webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "Component"></webobject>
   </webobject>

   <webobject name = "HasPrefix"> <webobject name = "Prefix"></webobject> </webobject><webobject name = "LastComponent"></webobject>
 </webobject> 


Components: WORepetition
{
  count = count;
  index = index;
};
 IsMain: WOConditional{
   condition = isMain;
};
 IsNotMain: WOConditional{
   condition = isMain;
   negate = true;
};
 ainLink: WOHyperlink{
   action = getMail;
   title = "get new mail";
};
 MainLabel: SpanString{
   value = "get mail";
   isSmall = true;
   isUpperCase = true;
  //isBold = true;
  class = "Label";
  length = 30;
};

 HasPrefix: WOConditional{
   condition = hasPrefix;
};
Prefix: WOImage{
   src = prefixUrl;
   border = 0;
   align = "middle";
};
 Component: Link{
   value = component.object;
   description = component.title;
   altDescription = component.title;
   value = component.object;
   pageName = component.pageName;
   isUpperCase = true;
   isSmall = true;
  //isBold = true;
  class = "Label";
};
 LastComponent: SpanString{
   value = lastComponentTitle;
   isSmall = true;
   isUpperCase = true;
  //isBold = true;
  class = "Label";
  length = 30;
}; 

That's all folks.
