[Zope] Yet another: How do I create linked path trails as per zope management interface?ement interface?

[Loren Stafford]

Here's how I did it. Most of the logic deals with some complications
introduced by Confera topics (meta_type == 'Message').

<!-- Start Breadcrumbs -->
<!--#unless expr="PARENTS[0]==PARENTS[-1]"-->
<!--#call "REQUEST.set('reverse_PARENTS', [])"-->
<!--#call "REQUEST.set('reverse_LAST', 0)"-->
<!--#in PARENTS skip_unauthorized-->
<!--#if expr="(meta_type == 'Message') or (meta_type == 'Reply')"-->
<!--#unless "reverse_LAST==1"-->
<!--#call "reverse_PARENTS.insert(0, _['sequence-item'])"-->
<!--#call "REQUEST.set('reverse_LAST', 1)"-->
<!--#/unless-->
<!--#else-->
<!--#call "reverse_PARENTS.insert(0, _['sequence-item'])"-->
<!--#/if-->
<!--#/in-->
<!--#in reverse_PARENTS-->
<!--#if sequence-start--><a href="/">Home</a>
<!--#else-->
 <!--#if sequence-end-->
  <!--#unless expr="(meta_type == 'Message') or (meta_type == 'Reply')"-->
 &gt;&nbsp;<font size="+0"><!--#var title_or_id--></font>
  <!--#/unless-->
 <!--#else-->
  <!--#if expr="(meta_type == 'Message') or (meta_type == 'Reply')"-->
 &gt;&nbsp;<a href="<!--#var absolute_url-->"><!--#var title_or_id--></a>
  <!--#else-->
 &gt;&nbsp;<a href="<!--#var absolute_url-->"><!--#var id--></a>
  <!--#/if-->
 <!--#/if-->
<!--#/if-->
<!--#/in-->
<!--#/unless-->

<!-- End Breadcrumbs -->
