I didnt think of this. But to understand the retraction, one has to see the code of the JessListener Java class. So if u look at the Jesscode, you won't understand or or when the retraction happens. In a sense, it happens 'outside' the reasoning of Jess. Then again, my rule isn't readable whatsoever anyway, so I think I'll stick wity your solution. Thanks!
