[Pharo-dev] in Pharo4.0,Latest update: #40581: push down -> DNU

Hi When I select an instance method and use push down in a subclass without obvious conflicts. I get two DNUs. realClass ^baseClass realClass theMetaClass dnu: theMetaClass while baseClass is a class realClass -> nil the environement does not contain the class. Now I did a class rename before and I wonder if it is not the one that is broken :( Stef
