[Plone-Users] Can't get next/previous links to display in my custom content type.

[Krys D. <kr...@kd...>]

Hi All.  I've got a folderish custom content type whose contents I'd like
to be able to browse through using next/previous navigation.  The expected
links, however, do not appear.  I have put debugging statements in the 
actual code in plone/app/layout/nextprevious (in view.py, links.pt, and
nextprevious.pt, to be specific).  Here is what I (think I) know:

1. The problem is independent of my type's display template.  The links don't
appear using the standard plone displays either. Turning the viewlet on & off
through use of @@manage-viewlets makes the debugging text in the page template
disappear & reappear as expected in my custom template.
2. The code in view.py finds the next and previous objects to display and is
aware of the fact that next/previous navigation is enabled. 
3. The code in links.pt and nextprev.pt is not getting values for view/next or
view/prev despite what the python code shows.
4. I've checked the list of interfaces provided by my content type against the
list for a folder in portal_types (ZMI). I don't see a difference.
5. The links work as expected for the standard folders in my site.

Does anyone have any ideas?

TIA,
Krys
