I *think* I've got the same problem - the thing is that interfaces inheriting 
from container interfaces inherit the __name__ and __parent__ attributes. And 
the formlib classes try to set up widgets for these attributes, which results 
in a component lookup error.

I simply omitted these two attributes, which solved the problem.
