Title: Fix for "Create and add another" button when using inherited classes

Related to recently submitted PR #815. Thanks to @michelsalib and @rande for getting this very useful feature implemented.

When you click the "Create and add another" it currently does not append the "?subclass=xx" to the url and you get an error on the subsequent page. This PR should fix this.
