Yes, your conclusion is correct. Combining views along an inheritance
relationship is unfortunately not as simple as it seems. In your case,
you probably want to see the attributes of the super class first and
then the attributes of the sub class. But this is not the only way to
go. Therefore, by default, we create a view model for every entity.
However, it is possible to programatically include things from super
classes. We have several custom solutions for this in place. I think the
best solution is to add something like a "referenced view" to the view
model. This could point to the super class. It would allow to specify,
where the attributes of a super class would be rendered within the layout.
