  • javax.faces.application.ViewExpiredException: View could not be restored I have tried all the solutions but couldnt get the exact solution can you guys help me out – ramu Apr 01 '16 at 03:20
  • In fact, your question is very broad. *Nothing* in your question gives a clue as to the real cause. The duplicate explains exactly when and why a `ViewExpiredException` will be thrown. Based on lessons learnt from the duplicate, you must be able to naildown the cause. Finally just reframe the question to ask how to solve that cause. – BalusC Apr 01 '16 at 07:42
