[Cppcms-users] Reporting validation failure reasons back to users

[doug l. <bi...@gm...>]

Hi -- I was just wondering if there's a mechanism for reporting detailed
form validation failure reasons back to the user?
I've been digging around in the tutorials and API docs & haven't found one.
The tutorial on forms shows how to set up validation on a form, but that
form just redisplays if the validation fails.
In RoR, validation also adds errors to a collection whenever a validation
constraint fails.
Is there something like this in cppcms, or is this something the framework
user should implement themself?
If so, is there a recommended way of reporting validation errors back to
the user?
Thanks,
   Doug.
