All right, I certainly don 't want to change anything to the initial
filtering capability, because there are already usecases as is. What I
was thinking of was an optional enhancement. The more I think on this
one, the more I think events are more appropriate when dealing with
security (the JACC stuff does not work, but a proprietary one should
most likely).
Let's forget the filter enhancement.
PS: a wrong slide plus a flawed memory made me claim on a meeting that
get and load where affected by filters, so I wanted to know the exact
reasons of this choice :-)

We were just talking about the delete use case last night in relation to
bulk deletes. I think it really comes down to how we want to
conceptualize the filters. Initially they were envisioned solely as a
mechanism for filtering returned data. What we are talking about here
is a serious expansion on that original conceptualization with serious
ramifications in terms of caching.
The one that is really difficult is the get/load scenario, as that then
supposes extension out to to-one associations.
Not sure how a filter (where condition) would even play into an
insert...
Even with deletes though, I can see what you are saying if the filters
are security-based, but what if the filters are temporal. Do we really
want to limit the deleted rows there?
At any rate, I'd prefer instead that this kind of stuff were handled
through the events like the JACC stuff does.

Subject: [Hibernate] Enhanced filtering?
I get some feedbacks from users using filters. Some of them seems to be
*keen on* enhancing the filter capability to all session operations
- load/get
- save/update
- delete
It makes sense for permissioned data as a global filtering. The thing is
that it needs to lower Hibernate capability (workaround update counts
breaking etc, versioning issue). What do you guys think of that?
