Hello Emmanuel,

this sounds like solid advice, thank you very much.

I wrote the following code following your example but it seems there is 
an error somewhere.

"TicketPreview" shows up in the Search/Results.html table but the cell 
is empty for each row.

On a sidenote (and without intention to blame you for anything) RT 
development is horrible to debug. :)

I attached 2 screenshots.

$ cat local/Callbacks/Univie/Elements/RT__Ticket/ColumnMap/Once
<%init>
$COLUMN_MAP->{TicketPreview} = {
     title => 'TicketPreview',
     value => sub { return loc($_[0]->TicketPreview) }
};
</%init>
<%args>
$COLUMN_MAP => undef
$GenericMap => undef
</%args>


$ cat local/lib/rt/Ticket_Local.pm
package RT::Ticket;
use strict;
use warnings;
sub TicketPreview {
     my $self = shift;
     my $content = 'foobar';
     return $content;
}
1;


$ cat local/Callbacks/Univie/Search/Elements/BuildFormatString/Default
<%init>
push @$Fields, 'TicketPreview';
</%init>
<%args>
$Fields => undef
</%args>
