        PageManager pageManager = resourceResolver.adaptTo(PageManager.class);
        if (nonNull(pageManager)) {
            Page listPage = pageManager.getPage("/etc/acs-commons/lists/practice/global/interests");
            GenericList list = listPage.adaptTo(GenericList.class);
            for (GenericList.Item item : list.getItems()) {
                if (StringUtils.equalsIgnoreCase(item.getValue(), value) &&
                        StringUtils.isNotEmpty(item.getTitle(locale))) {
                    LOG.error("Localized Title = {}", item.getTitle(locale));
                }
            }
