[jboss-user] [JBoss Seam] - Re: Session context variable missing

Thank you so much for your reply Peter.
Specifically helpful is the netiquette on posting.

I am still trying to wrap my head around bi-jection and scopes.

Is it true that during injection, SEAM will lookup a named component in all scopes based on the well known precedence (STATELESS, EVENT, PAGE, ...)?

I thought that by default, SEAM will outject to the same scope that it injected from.  
My thinking was that for every function call on my SFSB, SEAM would inject currentCategory from the SESSION,
let it be changed by the SFSB and outject it back to the SESSION.

I want whatever Category the user selects to be reflected in the session.

How about this approach?

  |     @DataModel
  |     private List<Category> categories;
  | 
  |     @DataModelSelection
  |     private Category selectedCategory;
  | 
  | ...
  | 
  |     @Create
  |     public String init()
  |     {
  |         if (currentCategory == null)
  |         {
  | 	currentCategory = (Category) em.createNamedQuery("Category.findRoot").getSingleResult();
  |         }
  |         return "success";
  |     }
  | 
  | ...
  | 
  |     public void select()
  |     {
  |         currentCategory = selectedCategory;
  |         return;
  |     }
  | 
  | ...
