[Zope-dev] The field converters (:int, :text, etc.)

[ender]

my alpha quality dtml-contract tag does allows custom field converters much 
as has been requested here, its meant as a generic form processing engine 
with the ability to define per variable error pages. its got some other 
features. its modeled on the arsdigita (acs) ad_page_contract.

due to my stupidity you have to add a custom filter directly to the filter 
dictionary defined in Filters.py.

fyi for the license impaired its gpl'd
