[EP-tech] Re: undefined value error

Not seen this before.  Does this script work:


#!/usr/bin/perl -I/usr/share/eprints3/perl_lib

use strict;
use warnings;

use EPrints;

my $ep = EPrints->new();
my $repo = $ep->repository( "myrepository" );
my $eprint = $repo->eprint( 1 );
$eprint->set_value ("title", "a value");
$eprint->commit;

I test-ran it on a 3.3.12 repository, and it worked.  First run as above, and then change the set_value line to use the new field.
