[Pharo-project] Refactor method

[Dario Trussardi]

Hi,

        i work with Pharo 1.0.

        I have a DTRConfig class with class method 'pippo'.

                When i select on it     the menu option:                
refactor method / pushdown      option  

                the system display the message:         DTRConfig class is not 
one abstract class


        I don't understund because it.

        On other class  the      refactor method /  pushdown    option          
        work fine.


        Thank for any considerations.

        Dario
