I am using Seam in a very important project of my company. In my project I need a base entity class and it has more than ten sub entity classes. I don't want to use single table strategy because the number of fields of the sub entities vary widely. But if I use the joined subclass strategy, a query for the base entity will always be polymorphic and will join all the sub entity table. This is very inefficient apparently. Is it possible to avoid this problem?
Sorry. I should post this topic to the user forum.
