Well, I found the error myself - and it was very silly, therefore I did not post a solution: My class which implemented the interface, was declared twice, the second overwrote the first one and missed the "implements()" statement. So the very simple problem was that my object did not implement the interface. It's still my big problem that I need a long, long time to decipher various errors thrown by Zope3. In this special case I had to look through the formlib/schema source code, which is not easily understandable to me due to the interface/adapter patterns, which still leave me puzzled in various cases...
