I'm using: Pharo2.0 Latest update: #20625 I'm at "Reflection continued When I do the command to go to the next lesson: ProfStef default executeMethod: (ProfStef lookupSelector:#next). I get the error: ProfStef(Object) doesNotUnderstand: #executeMethod When I browse to the class in the system browser, ProfStef doesn't have an executeMethod object. I also checked Object and ProtoObject,just to be sure, but neither of them listed an executeMethod either. P.S.: I also looked at the Class Methods, though default looks like it returns an instance, so that didn't feel reasonable. Where is executeMethod supposed to reside, and was this an intentional change that just hasn't propagated yet ('m guessing the removal of the method) or is something wrong with my image? Also, if I wanted to include it into ProfStef, what would the method look like? -- Charles Hixson
