I have not studied the context of this code but to me it looks suspicious.
If such a typecast is needed then something is wrong in the code's design.
An obvious idea is to change the AForm's type to IDesignedForm.
My intuition says that Sven's commit only revealed some fishy code in
sparta dockedformeditor.
