I need to filter historical data (i.e. there is a flag in the database that says whether the record is active or not). So the first idea that comes to mind is of course use a filter-def which would be awesome but the object i want to filter on is a subclass and is using inheritance mappings. It appears that you can't attach a filter-def to a subclass so I'm wondering what my alternatives are. I read the documentation and poked around on the forums and it seems that maybe this same functionality can be implemented using an interceptor or event listener but I'm not clear on exactly how. If anyone has had experience with a problem like this I would appreciate any suggestions. Thanks.

look at the where attribute
