[Zope] Product Problems w/ Zope.2.1.0 final

[scott kaplan]

I have been poking around trying to get squishdot to work with the
latest zope and I have got it working but I am not sure why it works, I
thought if I explain what I did, to get it working, and the error I was
geting, some of you Zope gurus could explain to me what I did, because I
can't figure it out.

When you add the squishdot product and it begins to create an instance of
a squishsite, it would give this error message:

Error Type: TypeError
Error Value: call of non-function (type module)
(i have added the traceback at the bottom of the message)

What I did was change the file TextIndex.py in the
Zope-2.1.0-linux2-x86/lib/python/SearchIndex

and commented out the line
209 : BTree = BTree.BTree

and changed lines
253: self._index=BTree()  to  self._index=BTree.BTree()
and                                                   
264: self._index=BTree()  to  self._index=BTree.BTree()

and now it works fine, no problems, so my question is, what did I do? It
seems like
BTree=BTree.BTree
self._index=BTree()

is the same as
#BTree=BTree.BTree
self._index=BTree.BTree()

So I am not sure what the difference is,

here is the traceback of the original message:
Traceback (innermost last):
