i have looked at smolder dfv error message handling before. i don't like to put
the error messages
in template. felt like hardcoded it too. esp when you have to do bunch of [% if
err_a_filed %] ..
[% ELSIF missing_a_filed %] ...
but it does give you the real flexiablity of setting up customized message.
one question though, if a field (say username) required at least lenght of 6
and contain only
number and alphabet. how do you show different error based on user input for
this single filed?

i sorta does it in the dfv form profile, i.e i do
msgs => {
constrains => { html_tag_found =>
$self->config_param('form_err.html_tag_found') }
}
but i am looking for a way to do it somewhere else.. will have to look at
krang's message class.
thanks!
