Yes, it works for error messages, thank you very much (I've also made
a mistake with enumeration - I should start input id from 0, not 1).
The only problem left was defaults, but I've used variable_encode and
it works like a charm.

In case anyone is interested:

Oh, and by the way: FormEncode sphinx documentation has invalid links
from built-in search engine. For example:

http://formencode.org/search.html?q=NestedVariables&check_keywords=yes&area=default

Gives link to:

http://formencode.org/modules/variabledecode?highlight=nestedvariables
instead of proper:
http://formencode.org/module-formencode.variabledecode.html

Thank you all for your help!
