[Thu Jul 02 17:47:30 2009] [error] Can't use string ↵
("cpmetinsegfilo") 
as an ARRAY ref while "strict refs" in use at 
/usr/share/eprints3/perl_lib/EPrints/Plugin/InputForm/Component/Field/Subject.pm 
line 88.\n

I've a field defined as:

                           {
                             'top' => 'scuole_specializzazione',
                             'render_input' => undef,
                             'browse_link' => 'scuole_specializzazione',
                             'name' => 'scuole_specializzazione',
                             'multiple' => 0,
                             'type' => 'subject'
                           },

which is used for the type "scuole_di_specializzazione":

    <epc:if test="type = 'scuole_di_specializzazione'">
      <component type='Field::Subject'><field 
ref="scuole_specializzazione" /></component>
    </epc:if>

In Eprints 3. The data has been migrated from an Eprints 2, and 
correctly loaded, I can see it in mysql.

 But when I try to display the stage where that field is, I get the error:

[Thu Jul 02 17:47:30 2009] [error] Can't use string ↵
("cpmetinsegfilo") 
as an ARRAY ref while "strict refs" in use at 
/usr/share/eprints3/perl_lib/EPrints/Plugin/InputForm/Component/Field/Subject.pm 
line 88.\n

I've that field in mysql:

mysql> describe eprint;

+-------------------------------+--------------+------+-----+---------+-------+

| metodologie_chimiche                 |
| scuola_specializzazione_bibliotecari |
+--------------------------------------+
4 rows in set (0.10 sec)

I can't understand where is the error... :)

 Please help :P
