OK. I wonder if the following would work for you:
{code:java}
SearchCondition<CriteriaQuery> search =
SearchContext.getSearchCondition(CriteriaQuery.class);
CriteriaQuery query = search.getCondition();
//pass it to JPA
{code}
Try that please.

Indeed, expressions like "bean.sub-bean.property=gt=5" are not supported yet.
InjectionUtils has the code for populating a given bean instance based on
expressions like 'bean.sub-bean.property'. If you can somehow reuse that and
provide a patch then it would be good.
