OK. I think I've got the "breadcrumbs" nav-stack method working right, if not working elegantly, on Confera Topics. Try it at http://209.67.167.51/Quena/Discuss. I added the meta_tag tests. I also added some debug info that shows up if you do View/Source in the browser. The wierd thing is that the meta_tag of a Confera Topic is different depending on your location in the topic: - If you're at the top of the topic, it's "Confera Topic" (as you would expect). - If you're at a message, not only does the message have a meta_type of "Message", but the containing Topic object says it's meta_type is ALSO "Message". (Similarly for replys.) Is this an example of "reverse acquisition"? The result in the script is a lot of extra logic just for Confera Topics. Is all this worth a How To entry? -- Loren. <!-- Start Breadcrumbs --> <!--#unless expr="PARENTS[0]==PARENTS[-1]"--> <!--#call "REQUEST.set('reverse_PARENTS', [])"--> <!--#in PARENTS skip_unauthorized--> <!--#call "reverse_PARENTS.insert(0, _['sequence-item'])"--> <!--#/in--> <!--#in reverse_PARENTS--> <!-- Debug <!--#var sequence-index-->: <!--#var sequence-item--> : <!--#var meta_type--> --> <!--#if sequence-start--><a href="/">Home</a> <!--#else--> <!--#if sequence-end--> <!--#unless expr="(meta_type == 'Message') or (meta_type == 'Reply')"--> > <font size="+1" color="#990000"><b><!--#var title_or_id--></b></font> <!--#/unless--> <!--#else--> <!--#if expr="(meta_type == 'Message') or (meta_type == 'Reply')"--> > <a href="<!--#var absolute_url-->"><!--#var title_or_id--></a> <!--#else--> > <a href="<!--#var absolute_url-->"><!--#var id--></a> <!--#/if--> <!--#/if--> <!--#/if--> <!--#/in--> <!--#/unless--> <!-- End Breadcrumbs -->
What I don't know how to do is test the type of the current object from inside an <!--#in--> loop. That is, how do I test if sequence-item is a 'Folder', 'Confera Topic', 'Message', or what? Can you help?
Use it's meta_type:
<!--#in sequence_of_objects--> <!--#if meta_type == 'Folder'--> I am a folder <!--#/if--> <!--#/in-->
