I just found out that my applications included JSF 1.2 library in war.
For some reason programmer in Kiev enabled related check box (JSF 1.2 package) in properties of the projects. I was really sure that we don't use JSF 1.2 because applications using facelets that included in JSF 2.0. So look likes we used two version of JSF in one application and it works :)
By the way maybe it's time to include JSF 2.0 library in Netbeans 6.5
Best Regards,
Vladimir
