In my (limited) experience: EntityHome is most useful when you need to do CRUD operations on a single entity. It makes it super-convenient if you do things the "seam-gen way". If you don't want to do things that way, it can be hard to work with. So, for example, if you want a component that does CRUD simultaneously on multiple entity objects, then I think you're better off with an EntityController. EntityHome extends EntityController, by the way, which is why most of the methods are the same. EntityController really just provides a ton of convenience methods. I find that I use EntityController more often than EntityHome. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091726#...
