Hi, ok now I'm going a little crazy. I've worked at this problem yesterday for about 5 hours. This morning as I just run the UnitTest again, without making any code changes it works. I'm developing on firefox and always use the shift+refresh option. As far as I know this should clear the cache, right? But obviously this seems to be a problem with the firefox cache.
I'm very sorry about that, but I was going crazy yesterday evening, because of this behaviour! Again: Now it seems to work, without changing even one line of code...
