I am thinking about a way on how to transfer data objects across several
managed-beans. Say I have two wizard pages, each having managed beans as their
"controller". Now both want to modify a DTO that comes from the business layer.
Now how do you pass the modified DTO from the first backing bean to the second?
Using managed properties my first approach was to inject #{firstBean.dto} into
#{secondBean.dto}. However, this creates a dependency on the order (what if
page 2 becomes page 1?). I would like to inject #{dto} only. So, this raises
the question: Why not make the DTO become a managed bean? Are there any
disadvantages? I have not seen this approach in any JSF tutorials. What if the
DTO becomes a, say hibernate, entity. Will the JSF lifecycle methods make this
impossible?
Thanks for any help
Chris
