I have been trying unsuccessfully to alter the text of the message in the bulk submit. The code, place inside _views_bulk_operations_direct_process ,producing the message is:
$context['results']['log'][] = t('Performed %operation on @items.', array(
'%operation' => $operation->label(),
'@items' => format_plural(count($entities), '1 item', '@count items'),
));
How can I modify this? The message is displayed on any change made on the bulk view by the edit form(hook_form_views_form_og_members_admin_default_alter).
