dont worry.\Tell us more what is the problem you fix because it is probably something for lukas :)

What I've done:

1. open refactor > code critics. Change every ParserTreeSearcher to RBParserTreeSearcher when debugger signals an error.

2. do "RBTransformationRule initializeRecursiveSelfRule" to initialize ��RBTransformationRule RecursiveSelfRule class variable ��(hihi I've learned to play with the debugger to find this one :)
