Hi Folks,

Hmm, answering my own questions here!

Out of curiosity I changed the commeted line to:

                 if( $results->valid( $col ) eq '' ) {
                     $them->$col( '' );
                 } else {
                     $them->$col( $results->valid($col));
                 }

And this worked, so I had a look into Data::FormValidator::Results.  
In there valid check to see if an array is required as a response. It  
will be if valid is called as a method parameter. If this is the case  
then valid calls an internal function _arrayify which does a nice  
little thing if the given value to arrayify isn't an array ref:

     return (length $val) ? ($val) : ();

Hmm... doh!

Not sure if this is working as intended or an issue... anyone know?
