[jboss-user] [JBoss Seam] - Re: Beginning conversations in @Factory methods

A user can click on an object's name to select it and bring up an update form or use a button below the list to bring up a form for new object creation.  When either of these forms is successfully submitted, the user is returned to the page with the DataTable

So you have

(1) A conversational search screen 

I usually recommend that search screens be page scoped, session scoped, or even purely stateless.

(2) A conversation that edits the data and then returns to the search screen 

Shouldn't it be a nested conversation then?

(3) the need to update the search screen when done editing the data 

why not just use a Seam event that forces refresh of the list (just like the booking list in the booking demo)


Have I understood everything here?
