Thank you for your reply
My test setup is:
. fedora 11
. python 2.6
. formencode in site-packages/formencode
(had to add the i18n directory) from [2]
. webware-1.1.b1
. using utf-8
I got the example from a direct download from formencode.org:
. [2] svn co http://svn.colorstudy.com/FormEncode/trunk FormEncode
(examples directory: WebwareExamples/index.py)
. you may switch language for formencode in awake
. some lines in "save" are experimental
My aim is to have a basic example I can use for my next steps.
Regards
Georg
