Hi, The code bellow should move all methods to a 'code' protocol. It works on some classes but not with all. In the later it results in a "no message" protocol. I can't find a reproductible case on the system classe, it may break in a class, then on a retry may not break on the same class. However applying twice the code bellow to the same class result in a no message protocol every time "Buggy" org := MyClass organization protocolOrganizer. org addProtocolNamed: 'code'. org allProtocols do: [:aProtocol | org moveMethodsFrom: aProtocol name to: 'code']. org removeEmptyProtocols. -- Dr. Geo http://drgeo.eu
