[Zope] trouble with #with and DTML documents

[Wolf Logan]

i'm having a strange problem (well, it's strange to me). i have a folder
called "newFolder". it contains a folder called "subFolder". "subFolder"
contains a DTML document called "DTMLDoc". "DTMLDoc" has a string property
"foo" that reads "this is the message". the "index_html" of "newFolder"
looks something like this:
-----
<!--#with subFolder-->
<!--#with DTMLDoc-->
<!--#var foo-->
<!--#/with-->
<!--#/with-->
-----
but this doesn't work -- it raises a key error. if the <!--#var foo--> line
is replaced with <!--#var title_or_id-->, it returns "subFolder".
apparently, the second "with" (#with DTMLDoc) isn't working properly.

now, when the key error is raised, it's raised from within DT_With.py, so i
know the right code is being called. i just don't understand why i don't
have access to the DTMLDoc's namespace from there.

any pointers?
