Thanks very much for this Carl, your insight pointed me in the right direction. It seems there are some caveats in the way I've been reading CGI vars which affect multi-valued parameters.
>From http://perldoc.perl.org/CGI.html -- When using this, the thing you must watch out for are multivalued CGI parameters. Because a hash cannot distinguish between scalar and list context, multivalued parameters will be returned as a packed string, separated by the "\0" (null) character. You must split this packed string in order to get at the individual values. This is the convention introduced long ago by Steve Brenner in his cgi-lib.pl module for Perl version 4. -- So it may in fact be possible to use $form_input to populate a formfu object with multi-valued parameters, as long as the packed string with "\0" dealt with. Still, I may just do it they way you've suggested in order to keep things clear and obvious. -Bobby On Sat, Nov 5, 2011 at 6:35 PM, Carl Franks <fireart...@gmail.com> wrote: > On 4 November 2011 19:24, J.
