[elephant-devel] make-instance with :from-oid

 LG> So when I use an oid that stores an object that is not of the given 
class, there is no error thrown or no warning.

of the given class?

You shouldn't use make-instance with :from-oid initarg to recreate 
instances -- it won't work correctly.

Use controller-recreate-instance function. It needs only oid and finds class 
automatically, so you just won't have problems with mismatches.
