[Zope-dev] Re: __setattr__ and acquisition ( was RE: __getattr__ and acquisition)

AFAIK acquisition bows out quietly during __getattr__, __setattr__.
You'll have to find another way to pass in the "thing" values before
__setattr__ gets called.

Maybe try an explicit self.aq_acquire('thing'). Maybe that would work.
