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_)
{
MapaMap_=_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,ineachconcretepageyoucouldinitializethepathcomponents:

protected_void_initPathComponents()
{
EnvelopeanEnvelope_=_this.value();
DateaDate_=_anEnvelope.creationDate();
ListaList_=_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:


{panel}
 <webobject name = "IsMain">
   <webobject name = "MainLink"><webobject name = "MainLabel"></webobject></webobject>
 </webobject>
 
 <webobject name = "IsNotMain">
   <webobject name = "Components">
     <webobject name = "HasPrefix">&nbsp;<webobject name = "Prefix"></webobject>&nbsp;</webobject><webobject name = "Component"></webobject>
   </webobject>
 
   <webobject name = "HasPrefix">&nbsp;<webobject name = "Prefix"></webobject>&nbsp;</webobject><webobject name = "LastComponent"></webobject>
 </webobject>
{panel}

  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.
