I have a problem in JSf Manage Bean when i edit a page

[Mark Kafe]

I want to edit a page, and use a same Manage Bean that i use for Save a page.

But when i define Manage bean scope request in Face con-fig then all values show null on Edit Grids...........If i change it to Session scope then its working fine..........


can any body help me about that problem........why this happen in Request scope???

The problem is that request objects exists only for the life of that particular request. It's especially a problem when working with tables, since the table model (and its cursor) is used to display the table, but no longer exists when you want to work with a row in the table.

The solution is to use session scope. As a rule, JSF does require more items to be in session scope than other J2EE frameworks.
