Hi all,
I am having a dropdown menu which is getting values from a previous page result and displaying it properly in my second page. But when i submit my second page i am getting following error. I am adding results to a model bean in first page action and accessing same model bean in my second page.My bean scope is request scope.

E SRVE0026E: [Servlet Error]-[Faces Servlet]: java.util.NoSuchElementException
