Spring Injected Models
Spring Injected Models and Seam
I'm trying to use a Spring-defined service and framework/model layer that I have created and jarred up from a separate project to be reused in the Web layer of my application. Using my service objects have worked flawlessly, I was able to retrieve objects from my service layer and show them in a table without an issue. Now I'm trying to use Seam to create a new account for a user on the web layer by injecting an 'Account' model object from my Spring definition of a JPA/Hibernate POJO.
The problem I'm seeing is that Seam appears to be injecting a fresh account into my RegisterBean with every request. How do I set up the RegisterBean with one Account object that'll stick around until I'm done registering the user? (Note that I'm using a4j's support to re-validate the Account object with every onblur, so it'll need to stick through that).
Am I going about this completely wrong? I'm new to Seam, but not JSF, so I have enough knowledge to be dangerous, but really am still grasping to understand the state/stateless nature of doing this with POJOs instead of EJBs. I really don't want to have to rewrite my Model objects as EJBs as the JPA/Hibernate POJO is working great in the rest of the app.
I'm including what I feel are the relevant code pieces to help you guys answer my question. If you need more info, please let me know and I'll post more of my config.
