The description of the objects in class B needs to be
instance
based. All the objects in one collection have the same description,
however class B is not able to provide a description.
You can override #description on the instance side to either build
your descriptions on the fly or to modify the ones returned by the
class. For example:
B>>description
^ super description collect: [ :each |
(each isKindOf: MAToManyDescription)
ifTrue: [ each copy classes: self dynamicClasses ]
ifFalse: [ each ] ]
