Hi!
I have a problem with xcos. I have created a superblock, which worked fine all the time, and suddenly I cannot access it anymore. After doubleclicking on it the console reads:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Can someone please give me a slight hint what may have happened?

THX!
