Hi prabhat,

NullPointerException only comes when Null is passed in session.
javax.faces.el.EvaluationException: In this case FacesContext must be
saved in the session and then you are reusing it. Thus it would not be
valid any more. If you are using session and trying to get it in the
next page when you press ancher link, then its getting null thats will
be the reason.
Please check the following:
1) Try to call FacesContext.getCurrentInstance()
2) You may save the context within a method in a variable also.
