Hey there... Well, I resolved this by creating a secondary dao and dao implementation (hibernate based) which kind of surprises me. Both managers and daos operate on the same domain model class and I really only needed the manager interface and impl but I couldn't figure out what was blowing up. When I created the secondary dao and added that in, no sweat, it just worked...
Matt, do you know why this is? I'm kind of surprised... For example, *both* of my daos and mgr's that operate on the single domain model class are probably sharing the same Generic manager and dao superclass, right? I'd love to have a clearer understanding of why this was a problem without the daos, if you're in the know...!! BTW, I love your ideas for the future of appfuse. I took a split second look at grails and a longer, client mandated look at seam and frankly, I couldn't sell many of our clients on either of those, compared to the Java EE standard that many of our (admittedly pretty corporate) clients are looking for. I also am wondering (& have been for a while) about the future of web UIs as currently implemented, SOFEA makes a lot of sense so GWT and / or flex (I'd prefer both I think) sound good to me... --j jackalista wrote: > > Hi, > > I want to create a secondary manager interface (i/f) and implementation > for an existing DAO and (hibernate) domain model class.
