I'm not sure I understand what you mean; I don't understand why your
adapted object would become detached from the original context.

It looks like you're losing acquisition context. You put an object into
acquisition context explicitly. Something along these lines:

import Acquisition

class MyAdapter(Acquisition.Explicit):
   def __init__(self, context):
       self.context = context

def getAdapter(context):
   # create adapter for context, and wrap it explicitly in the acquisition
   # context
   return MyAdapter(context).__of__(context)

This works to give the adapter among other things a security context,
so you can call methods on the adapter from a page template, for instance.
You can also get to REQUEST and such, though in this case I used explicit
acquisition so you'll have to use self.aq_acquire.REQUEST, if I recall
the syntax correctly.

P.S. In the course of the coming weeks I'll be backporting parts of Zope 3's
component architecture, especially adapters, into Zope 2. Contact me if 
you're interested. I also expect I'll be making more noise about this in
a few weeks.
