Re: [hibernate-dev] [OGM] OGM-21 query support
Hi Guillaume,
We have been discussing this issue (OGM query support via EM) earlier today
on IRC, as it's definitely one which we should fix soon. As you started to
work on it, do you have something worth sharing, which e.g. someone else
could take that as starting point?
Thanks,

Hi,
Maybe you could have OgmEntityManager implement
HibernateEntityManagerImplementor (its an interface, no class) and forward
it the HEMI methods to the wrapped EM instance?
