We are using Idea 5.1.2 with bundled SVN Repository. Some libraries are stored in repository.
After getting updated version of project Idea sometimes don't recognizes correctly classes form added libraries. Name of the class is empty (it's shown on attachment) and when I'm calling method of that class Idea can't find it; but project compiles and works perfectly. Also you can open that class from library by clicking it empty name, and it works, code of that class exists.
Any ideas:) what's wrong with Idea?
