[EP-tech] Setting a date (as a sub-field)

I'm extending my EPrints repository (EP 3.3.14) to hold multiple dates - 
so eprint_fields.pl has the following added:


      {
          'name'     => 'dates',
          'type'     => 'compound',
          'multiple' => 1,
          'fields'   => [
              {
                  'sub_name'       => 'date',
                  'type'           => 'date',
                  'min_resolution' => 'year',
              },
              {
                  'sub_name'    => 'type',
                  'type'    => 'set',
                  'options' => [ 'submitted', 'accepted',
                                 'published', 'completed', ],
              },
          ],
      },
(and do the database update, and add the various phrases, and restart)

I then run a bit of code to copy from $ep->{date} & $ep->{date_type}
into my new structure:

    my $ds = $session->dataset( 'archive' );
    my $list = $ds->search;
    $list->map( sub {
        my( $session, $dataset, $eprint ) = @_;
        my ($date, $type);
        ($date, $type) = ($eprint->value('date'),
                          $eprint->value('date_type'));
        if ($date) {
          my $new_date = {date => $date, date_type => $type};
          $eprint->set_value( 'dates', [$new_date] );
        }
        $eprint->commit;
	}
    } );

The problem is that some dates are coming out the system as '2011-02' or 
'2008' and this is throwing the set_value routine:

    Dates: $VAR1 = {
            'date' => '2009-11-09',
            'date_type' => 'published'
     };
     ERROR:  invalid input syntax for integer:
     "f75237ba80d51376a093ee1a825a42cd" at ../EPrints/DataObj.pm line 294.

  From http://wiki.eprints.org/w/Date_field this should work fine?

Any thoughts?
