Just uppdated IDEA to build 3339 and opened my project, 1 webappmodule and 2 standard java module. The problem is that in the project tab, both project tree view and J2ee tree view is gone, only package view is left. IDEA also reports 3 fatal errors "java.lang.RuntimeException: Operation is not supported". I still can open files if I use go to function.
Have anyone experience from this problem and a solution to it?
