Hello,
I want to get a List of latest JournalArticle for a given List of articleIds. I mean that I want to get the latest JournalArticle with the highest version. But for n JournalArticle with one query.
I try this
final Object[] array = articleIds.toArray();
final DynamicQuery query = DynamicQueryFactoryUtil.forClass(JournalArticle.class, PortalClassLoaderUtil.getClassLoader());
query.add(PropertyFactoryUtil.forName("articleId").in(array));
query.setProjection(ProjectionFactoryUtil.max("version"));
final List<journalarticle> dynamicQuery = JournalArticleLocalServiceUtil.dynamicQuery(query);
</journalarticle>
But get an Exception that Double can't be cast to JournalArticle. But how can I build a DynamicQuery to get a List of JournalArticle by max version?
regards Chris
