CriteriaSupport Injection
Hi guys,
For sake of simplicity, I'd like to use the following construct:
@Inject
CriteriaSupport<Entity> entityCriteria;
Is it possible? does it make sense for you?
We already do that (generic query execution) with EntityManager itself but
there is no criteria support.
thanks in advance.

Yea, I was migrating an old "utility" class to use deltaspike criteria and
just deleted it in favor of DS criteria ;)

I was actually just about to respond with "not sure it makes sense".
The reason being, we rely on an entity manager resolver in data to
determine which EM the repository is associated with. You would have no way
to differentiate criteria supports per EM as a result.
Plus its always better to put your DB logic in your DB tier.

Answering myself, Its possible (by extending CriteriaSupportHandler) but
not worth, better stick with inheritance with current api(which is great).
