[Zope] Can't access a method 'in this context'

Casey,

you were partly right... I had copied and pasted a very similar method (and
it's security) but only remembered to change the actual method definition
and not the security.

*However*, correcting this mistake seems to have made no difference at all.
I still receive exactly the same error message and traceback.  To be sure, I
deleted my product from the Control Panel (along with all instances),
restarted Zope (2.5.1 btw) and then tested again... no joy though :-(

Any more clues?  I've got to say, 'context' and acquisition type stuff (if
that's even relevant here) are pretty mysterious to me.

cheers
