I had a problem like this a few weeks ago.  When I discussed it with
alecm on #plone, he seemed to know what was causing the problem
(something to do with the form.action decorator storing objects in such
a way that acquisition got stripped).  Unfortunately, the appropriate
fix was, apparently, not obvious or easy.

The workaround that I employed was to simply declare my template as a
full-blown view and then look it up with getMultiAdapter instead of as
an attribute of the form.

Maybe alecm can remember more...
