Hello

I am making some modifications in the smalltalk meta-model and i need

to replace classes with Ring classes (it is supposed to be possible since they are polymorphic)

But i am having a little problem, all the classes know how to answer the message "isObsolete"

but Ring classes doesn't, to solve this i have defined the method "isObsolete" in RGBehaviorDefinition

but i am not sure which code does it need

- if i copy and paste the code from Behavior, then i obtain more "doesNotUnderstand" messages

since the code from Behavior>>isObsolete is "self instanceCount = 0" but Ring classes doesn't know how to answer "instanceCount" neither

so i suspect this is not the right way to do it.

- if i copy the code from Class, then it seems it works, but the result from for example

"Array isObsolete" is different of the result from "Array asRingDefinition isObsolete" consequently�

next messages obtain different results and finally a a "doesNotUnderstand" message again.

Am i doing something wrong? Any suggestion?�
