Tim,
thanks for the reply: i should have made myself clearer the first
time round: at first i thought it was just an issue of stringifying
things in order to compare them, but, once this is taken care of (as
i suspect it is now) this fscking recursion error takes over. which,
IINM means its a namespace problem.
one of the things which puzzles me is that when i use objectIds() (as
opposed to objectValues()), the recursion problem goes away, but i
can't call the title variable without getting an authentication
dialogue (which doesn't accept the admin pwd!) - now, i can get round
this by using the title_or_id variable, but this renders as the
title_or_id of the *current* document times the number of documents
in the list (instead of the title_or_id of each document)! this,
again, IINM, suggests a namespace problem.
i guess i must be missing something fairly obvious because i can't
believe i'm trying to do something particularly strange :(
Folder_X [Folder]
standard_x_header [DTML Method]
nav_stuff_l1 [DTML Method]
nav_stuff_l2 [DTML Method]
Folder_Y [Folder]
doc_1 [DTML Document]
doc_2 [DTML Document]
standard_x_header includes
<dtml-var nav_stuff_l1>
<dtml-var nav_stuff_l2>
<nav_stuff_l1> is this:
<dtml-comment>
This method builds the 1st-level site navigation. It iterates through
Folder objects below the site root, sorts them by the property
"menu_sort_order" (which is an integer value starting at 0) and
renders the Folder title (this is important because we can't put
accents in the id) only if this property is present. The inside loop
tests whether the current folder is in the list of folders and
if it is it wraps square brackets around the title to highlight our
current position.
</dtml-comment>
<DIV CLASS=navigation VALIGN="top">
<dtml-in "Folder_X.objectValues('Folder')" sort=menu_sort_order>
<dtml-if "hasProperty('menu_sort_order')">
<dtml-if "this()==PARENTS[0]">
<a href="&dtml-absolute_url;">[<dtml-var title>]</a>
<dtml-else>
<a href="&dtml-absolute_url;"><dtml-var title></a>
</dtml-if>
<dtml-else>
</dtml-if>
</dtml-in>
</DIV>
<nav_stuff_l2> is this:
<dtml-comment>
This method builds the 2nd-level site navigation. It grabs the Folder
of the current DTML Document [index_html] and iterates through the
DTML Document objects inside it, rendering the document titles
(because of accents, we don't want to render the document id) sorted
by the menu_sort_order property. The inside loop tests the current
document id against the list of document ids in the folder and wraps
square brackets around the title to highlight the current document.
</dtml-comment>
<DIV CLASS=navigation VALIGN="top">
<dtml-let this_id=id>
<dtml-in "PARENTS[0].objectValues('DTML Document')"
sort=menu_sort_order>
<dtml-if "hasProperty('menu_sort_order')">
<dtml-if expr="_['sequence-item'].getId()==this_id">
<a href="&dtml-absolute_url;">[<dtml-var title>]</a>
<dtml-else>
</dtml-if>
<a href="&dtml-absolute_url;"><dtml-var title></a>
<dtml-else>
</dtml-if>
</dtml-in>
</dtml-let>
</DIV>
NB: <dtml-if expr="_['sequence-item'].getId()==this_id">
^^^^^^^
added as per Michel Pelletier's suggestion.
where the excessive recursion comes from i have no idea! :(
cheers,
Garry
