问题 I am displaying a list of items with links in my xhtml page. When I click my "back to previous page" button from that link, I basically reset the flags in my bean to indicate to the xhtml which page to display, and reload the list of links from my database. When I click the same link (or any other link for that matter) in this new page, I get this error: javax.portlet.faces.BridgeException: javax.portlet.faces.BridgeException: javax.faces.FacesException: Unexpected error restoring state for
