3:10 p.m.
I'm using Seam 1.1.6 with ICEFaces 1.5.3 I built a tree with a panel stack.
I need to be able to execute my business logic and then set the selected panel to the page
that will contain the generated output.
I can forward to the page by itself but, I'd like to stay on the page with the tree
and only replace the panel to the right of the tree.
Does anyone know how to gain access to a web bean from inside a stateless session bean?
Is there another way to do this?
