petemuir,
Thanks so much for your help. I've re-read the reference guide at
http://docs.jboss.com/seam/latest/reference/en/html/tutorial.html#registration-example
and I think I figured out where I was going wrong.
I found this:

| 1.3.2. How it works

| The first time we navigate to the messages.jsp page, whether by a JSF
postback (faces request) or a direct browser GET request (non-faces request),
the page will try to resolve the messageList context variable. Since this
context variable is not initialized, Seam will call the factory method
findMessages(), which performs a query against the database and results in a
DataModel being outjected. This DataModel provides the row data needed for
rendering the <h:dataTable>.
|
So, this implies that Seam knows which session bean to instantiate in order to
get the @Out messageList context variable, without needing to be told.
You don't need to use #{messageManager.messageList} because Seam knows to use
the session bean declared with @Name("messageManager") to get the value of
messageList to be outjected.
Alternatively, Seam can instantiate the session bean declared with in
@Name("todoList") but without outjected fields. These beans are part of the
Seam context, and can have methods run against them, using the
#{todoList.method} syntax.
Am I now thinking along the right lines?
