I hoped this would help narrow the 'access violation' issue:

- mixing isomorphic and polymorphic serialization seems to be problematic
whenever the object using isomorphic serialization is also a part of the
hierarchy for which we use polymorphic serialization.

- on the other hand, if the object belongs to a totally independent class we
do not have this issue. 

 

Is it possible this is also related to the registration of serializers?
