This may be obvious, but what we are going to need to do is assign the variable $news_messages somewhere other than news.php.
In modules/News_management/news_manage.php you will see the variable assigned to smarty:
Code:
$smarty->assign('news_messages', func_news_get($shop_language, false, false, "$first_page, $objects_per_page"));
Hope that helps,
