Nightmare ICEFaces!

I used ICEFaces framework to develop business web application.
My project completed 70%, ICEFaces alert update up to version 1.8.1 and stupidest that happened!!!

I updated to 1.8.1 without backup current my web, very risky. Finnaly, my web has some bugs that I can't know and investigate. I tried many times, it spended more time to analysis but everything seems want to against me. I am very disapoint about ICEFaces.

Today, try again, I continue go with another way to solve that problem, haha, thank my God, I suddenly find right solution, that downgrade and upgrade again. Wonderfully, it can fix itseft, I don't know what happen here, but I sure that it maybe good experience for future when facing similar one.

That luckily day!!!
