[Repoze-dev] chameleon.formish and formish i18n

[Tom Gross]

Hi all,

  what is the preferred form generation tool for repoze.bfg? I tried 
chameleon.formish, which seems a nice solution.

I found the fileupload-widget is broken, attached is a patch to fix it.

This is probably the wrong list to ask about i18n support of formish, 
but since chameleon is involved the key is maybe there. I solved the 
localization issue of the form labels with the following monkey patch, 
but I'm not really happy to use monkey patches in general. does anyone 
know of a better solution?

I wouldn't argue that it's better ...

I've been using formencode which has i18n support,
formencode.validators is easy to work with, the package has minimal
html generation (formencode.htmlfill) which was a design decision.
