[rt-users] XLS export balks

[Boris Epstein]

Hello listmates,

I have an RT 4.2.0 installation using Postgresql as DB engine running on a
CentOS 6 server where every attempt to extract a search to XLS results in a
failure.

The failure manifests itself in the following way. The user's browser
displays the following message:

*An internal RT error has occurred. Your administrator can find more
details in RT's log files.*

The Apache/HTTPD log displays the following:

*[27915] [Wed Sep  9 21:20:27 2015] [error]: Undefined subroutine
&RT::SQL::PossibleCustomFields called at
/opt/rt4/local/plugins/RT-Extension-SearchResults-XLS/html/Search/Results.xls
line 80.*

*Stack:*
*
[/opt/rt4/local/plugins/RT-Extension-SearchResults-XLS/html/Search/Results.xls:80]*
*  [/opt/rt4/sbin/../lib/RT/Interface/Web.pm:680]*
*  [/opt/rt4/sbin/../lib/RT/Interface/Web.pm:368]*
*  [/opt/rt4/share/html/autohandler:53]
(/opt/rt4/sbin/../lib/RT/Interface/Web/Handler.pm:211)*

Here is what I think is the relevant excerpt
from /opt/rt4/local/plugins/RT-Extension-SearchResults-XLS/html/Search/Results.xls

*...*
*my $col_entry = sub {*
*    my $col = shift;*
*    # in tsv output, "#" is often a comment character but we use it for
"id"*
*    delete $col->{title}*
*        if $col->{title} and $col->{title} =~ /^\s*#\s*$/;*
*    return {*
*        header => loc($col->{title} || $col->{attribute}),*
*        map    => $m->comp(*
*            "/Elements/ColumnMap",*
*            Name  => $col->{attribute},*
*            Attr  => 'value'*
*        ),*
*...*

Line 80 is the line that says: my $col = shift;

Has anyone encountered something like this? Any idea what this may be?

Thanks.

Boris.
