[Zope] Equality test: if sequence-item = document id [excessive recursion error]

[Thomas B. Passin]

Where are you setting this_id?  Are you doing it like Tim illustrated?  I
don't see it in your code fragment.

re this earlier post which i'm still having problems with, can anyone
enlighten me as to what could be causing this excessive recursion
error (and how to avoid it)?

cheers,

Hi Tim,

i don't understand why, but it doesn't work for me!

what i have is this:

a nav_stuff method:

<DIV CLASS=navigation VALIGN="top">
<dtml-in "PARENTS[0].objectValues('DTML Document')"
sort=menu_sort_order>
<dtml-if "hasProperty('menu_sort_order')">
<dtml-if "_['sequence-item']==this_id">
&nbsp;&nbsp;<a href="&dtml-absolute_url;">[<dtml-var title>]</a>
<dtml-else>
</dtml-if>
&nbsp;&nbsp;<a href="&dtml-absolute_url;"><dtml-var title></a>
<dtml-else>
</dtml-if>
</dtml-in>
</DIV>

which is called from the standard header.

the standard header and the nav_stuff method are in the same folder.
if i have a document in a subfolder which calls the standard header,
which in turn calls the code above, i get an excessive recursion
error.

any suggestions would be much appreciated!

cheers,

G
