I found a good explanation about the behavior of request scope in this link http://www.theserverside.com/news/thread.tss?thread_id=44186

If you are using ManagedBeans in request scope, you get problems with CommandLinks inside DataTables. DataTables are one thing I really like about JSF, and CommandLinks often come in handy as well. But when you put a CommandLink inside a DataTable, e. g., to select the entry of the row in which the CommandLink is, you get bitten. That is, if you want ManagedBeans with request scope. The action which should be triggered by the CommandLink is never triggered, the page is simply rendered again. The reason for this behaviour is that the DataTable modifies the id of the CommandLink during renderering, but the CommandLink does not know that it was rendered with a different id. During the decoding of the request which was triggered by clicking the CommandLink, the ComandLinkRenderer looks at a hidden form parameter. If the value of that form parameter equals the id of the CommandLink, an action is queued. If not, nothing is done. Since the DataTable changes the ids, the value of the hidden form parameter does not match the id of the CommandLink.

Based on above context, you need to change the scope annotations from @ViewScoped to @SessionScope, and your problem will be solved automatically. It seems to be a better solution than write additional code, unless you need to keep the @ViewScopped
