[ZPT] problems with RepeatVariable

[Lynn Walton]

I have the following:

<span tal:define="mainMenuTree python:here.mainTemplates.buildSiteMap()"

      tal:omit-tag="">

 <span tal:repeat="menuItem mainMenuTree" tal:omit-tag="">
     <a href="" tal:attributes="href menuItem/name">
    <span   tal:replace="menuItem/name"></span></a>&nbsp;
    <span    tal:replace="python: repeat['menuItem'].number">1</span>
    <span tal:condition="python: not
repeat['menuItem'].end">|&nbsp;</span>
  </span>

</span>

When I use python: repeat['menuItem'].number" I get
<method Iterator.number of Iterator instance at ecf6d4>  printed out
instead of the number.

When I use python: repeat['menuItem'].index" I get the proper index.

When I use repeat/menuItem/number  rather than a python: expression, it
works giving the numbers.
But I thought
"python: repeat['menuItem'].number" was supposed to be an allowable
syntax?

Likewise,
<span tal:condition="python: not repeat['menuItem'].end">
gives isn't working, because it seems to be returning <method
Iterator.end of Iterator instance at e937cc>  instead of true or false.

Can someone advise me on what I'm missing. I'm trying to follow the doc
at
http://www.zope.org//Wikis/DevSite/Projects/ZPT/RepeatVariable

I'm using PageTemplates-1-4-1
TAL 1.4.1
ZTUtils 1.1.2

Thanks,
Lynn
