JSF and request scope beans don't get along very well. JSF uses postbacks, and since request scope objects by definition (JSF or not) are created and destroyed on a per-request basis, they can't carry over data from one request (postback) to the next.
This led to a lot of people getting annoyed because they were being forced to use session scope for relatively short-lived objects. So in JSF2, view scope was added. View scope is a special type of session scope where JSF automatically discards the backing bean when the user switches to a new view.
