[Zope] ZCatalog (2.3.1) won't acquire method from parent folder?

[sean.upton@uniontrib.com]

Running Zope 2.3.1; A ZCatalog instance that I have won't acquire a method
from the parent folder it resides in; I get a NameError on the method.  This
is very strange.  The method is called from another method whose results are
supposed to be indexed.

+Zope Root
  +Classifieds	(Container, Subclassed from
				Folder, contains a method called
			  	iterateText(self, text, times))
     Catalog	(ZCatalog)
  
I have a text index set up for a method called searchTextWeighted, which is
a DTML template file on disk within a python product.  Inside
searchTextWeighted, I have the following DTML:
	<dtml-var expr="iterateText(getTitleExpanded(), 5)">

iterateText is a method of a python class that is subclassed from
ZCatalog.CatalogAware and OFS.Folder.Folder:

	def iterateText(self, text, times):
        	"""Repeats output of text times # of lines for # of times"""
        	result=''
		times=int(times)
        	for item in range(times):
        	  result=result+text+'\n'
        	return result

I get a name error for iterateText upon trying to add a catalog-Aware class,
when index_objects() is run (I just made this class Catalog-aware).  This is
weird, since, in terms of namespaces, iterateText is in a folder above the
Catalog, and also above the item I am trying to ad, so no matter how you
look at it, iterateText should be acquired, and not generate a Name Error.
In testing this out, I am able to traverse to iterateText via URL in a
browser with no problems.

I assume that this is not related to the ZCatalog bug in 2.3.1 where the
Catalog won't run a method requiring arguments.  The method in the index,
searchTextWeighted, passes all the arguments needed by iterateText in the
DTML.  So I am a bit confused here.

Traceback is below.
