Sorry - wrong screen - it is:

Error type:  NameError
Error value: methodA


One other thought (and I could be way off here), but Zope is responsible
for taking action based on the fact that "" was specified - why can't
the mechanism that takes that action just ensure for me that my
namespace is propagated into whatever I might be calling, ad infinitum? 
It is certainly very counter-intuitive that it would not (very Perl
like).
