The main problem with "B" is that "self.index_html()" almost surely
returns a string and a string does not have a method "absolute_url".

  Try: "self.index_html.absolute_url()" instead.

You can.

    zpt(a standard parameter list)

    You find your passed in parameters in the standard TALES variable "options".
    This is a dictionay. Positional parameters are available via
    the tuple "args" and keyword parameters are available via their
    key.

This has nothing to do with passing parameters...

   When a subsequent "listInstances" does not show newly created
   instances, this may be a cache problem.

   Force your browser to reload the page. Do you now see the
   new instance -- then it is a cache problem.

   Search the mailing list archives for "cache control".
   There is also a HowTo on Zope.org.
