hey ci team, first of all: thanks for this great framework.
I’ve a short feature request.
I got the line “Unable to access an error message corresponding to your field name.” and i wondered which field has been meant.
So could you change the line 658 of Form_validation class
from
$line = 'Unable to access an error message corresponding to your field name.';
into something like this
$line = 'Unable to access an error message corresponding to your field name: '.$rule;
tiny feature, but saves time 
bye,
velti
