QUESTION I got the following Debug-Message from a Script - Removed Class: ClassName does not understand method What did I do wrong and how can I solve this problem? ANSWER This problem in VisualAge is caused by deleting a class without removing all method references to it. You should be able to do "Browse References..." and find all the references to the class that no longer exists (if you deleted then recreated the class, simply recompile the methods referencing it). If this does not work for you, it's probably best if you are in the Team environment, to get a new image and reload your application. We have seen this before, and that is the fastest and best way to get rid of it.
