[Zope] REQUEST variables in exceptions

I have a DTML document with the following structure:
<p> Report that everything was ok and wait for ack.
<form method=POST action=index_html> <input type=submit value="OK"> </form>
<p class="warning"> Warn about problem found by external method.
<form method=POST action="treatError"> <input type=submit value="OK"> </form>
and it works wonderfully, to be honest I thought it was quite uncanny to define
and raise an exception inside the python module, and having it caught by the
Now, to improve the treatment of errors I need to refer, inside the
<dtml-except> block, to some variables that were defined in the REQUEST
variable (I'm pretty confident of this because I used them inside the external
method), but it seems that the original REQUEST variable is no longer set
inside the <dtml-except> block. Is this correct? What actually happens (in
simple terms, please :) when an exception is thrown?
I also tried the very few other tricks I know with DTML (<dtml-with
"_.namespace..."> outside the <dtml-try> block, plus some other voodoo) but
couldn't get it to work, either.
Should I return these values as error values with the exception? I can do it
if this is the only option, but I'm already using the return value for
information related to external method things, and I'd rather not mix the two
``domains'', so to speak.
Many thanks for any tips,
