I tried to set some values when reporting Item5798, but they simply don't apply. Probably it is related to TSA code. I need a test environment to solve this (unfortunately, I don't have one now).

The affected values are those from checkboxes. Radio buttons, text inputs, text areas and selects works well.

Investigating this issue, I find the problem within TWiki::Engine::CGI::prepareBodyParameters:

sub prepareBodyParameters {
    my ( $this, $req ) = @_;

    return unless $ENV{CONTENT_LENGTH};
    my %p = $this->{cgi}->Vars;
    while ( my ( $key, $value ) = each %p ) {
        $req->bodyParam( -name => $key, -value => $value );
        $this->{uploads}->{$key} = 1 if scalar $this->{cgi}->upload($key);

According to CGI.pm man page:

When using this(CGI::Vars), 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.

So the fix is to call $req->bodyParam this way:

$req->bodyParam( -name => $key, -value => [ split /\0/, $value ] );
