I'm using 8940 on Windows XP Pro SP2. I'm using RichFaces 3.2.2.GA which has tld files for the a4j and rich tags.
After using 8940 for a while, 8940 doesn't understand the rich tag (although it understood it before). If I close Idea and run it again, everything is fine. I even cleared the cache (delete everything in .IntelliJIdea8.0/systems) but that didn't help.
Does anybody know the reason?
