RoMEO:
After enabling RoMEO lookups in the admin panel and then navigating to a
citation I see this debug message:
Debug: Undefined property: IslandoraFedoraObject::$pid in
/var/www/html/drupal-7.15/sites/all/modules/islandora_scholar/islandora_scholar.module
on line 176 triggered via __get in MagicProperty->__get() (line 82 of
/var/www/html/drupal-7.15/sites/all/libraries/tuque/MagicProperty.php).
and this notice:
Notice: Trying to get property of non-object in RomeoView::getISSN() (line 32 of
/var/www/html/drupal-7.15/sites/all/modules/islandora_scholar/includes/romeo.tab.inc).
