JSF View The JSF view is comprised of two pieces: the view root and JSP pages. The view root is a collection of UI components that maintain the state of the UI.The JSP page binds UI components to properties of backing beans and buttons to event handlers and action methods.The Controller uses the view ID to look up the components for the current view. If the view doesn't already exist, the JSF controller creates it. If the view already exists, the JSF controller uses it.(Ques):Where will be the view be saved?

  1. ServletContext

  2. RequestScope

  3. FacesContext

  4. ApplicationScope
