I execute a named query with an alias to bean result transformer and EHCache query cache activated
Code:
Query query=session.getNamedQuery("Articles.byName");
query.setParameter("name",name);
query.setResultTransformer(Transformers.aliasToBean(ArticleVO.class));
query.list();
Code:
<query name="Articles.byName" cacheable="true">
<query-param name="name" type="string"/>
<![CDATA[
select article.id as idArticle, article.name as nameArticle,
from Article article
where article.name like :name
]]>
</query>
I get the following exception
