[Zope] BUG?? Acquisition && External Methods

[Samuel A. Falvo II]

Well, I upgraded to 2.0.0b4, and I think I found a bug, but am not sure. So
I'm posting it to the list for all to review first.

I have defined index_html as so in the root folder:

	<!--#var pre_content-->
	<!--#var content-->
	<!--#var post_content-->

This index_html file is shared throughout the website.  Then I define
pre_content so as to display banners and set up the tables for the rest of
the page layout.  The idea is that each folder has a "content" method, which
contains the meat of the page, with pre_content and post_content being
shared across all pages.

post_content closes the HTML tags opened in pre_content, of course, and
calls <!--#var copyright-->, which displays our company's copyright message.
The copyright method, in turn, makes a reference:

	<!--#var BASE1-->

Problem is, this *FAILS*.  I get the following tracebac (cleaned up from the
original HTML):

  Error type:	KeyError
  Error value:	BASE1

Traceback (innermost last):
  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 209, in publish_module
  File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 179, in publish

  File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: index_html)
KeyError: (see above)

Please note that I get this error with BASE, BASE1, URL0, URL1, URL2, etc.
NOW, if I create an external method:

	def PriceQuote( self, RESULT, RESPONSE ):
	   return RESULT

I find in the resulting display that BASE, BASE1, URL1, URL2, etc., -->ARE
DEFINED AND SET CORRECTLY<--.

Anyone care to tell me why Zope is being utterly boneheaded about <!--#var
BASE1-->??  I've been banging my head against the wall with this one for
hours.  I've got no choice but to hardcode a URL into the copyright code,
which is fine for now, but certainly not the ideal solution -- I'd really
rather have it as hardwired-free as possible.
