Is it possible to codegen classes that inherit from abstract superclasses?

I am trying to codegen matlab classes that inherit from an interface in which I have defined abstract properties that must be inherited. I tried to define the types of these properties, but I get the following error message:

"Size and validator functions not supported for properties defined as abstract in superclasses. Property 'myprop1' is defined as abstract property in superclass 'MySuperClass'."

I tried only validating the properties in the subclass, but the error message persisted. Is it not possible to define property types for classes that inherit abstract properties?
