Oh, I was trying with the classname optional parameter, and it
recreates an instance when there is no instance associated with the
oid.
ex: (ele::controller-recreate-instance *store-controller* 555555 'classname)

What I have been looking for is tihs:
(defun get-instance-by-oid (class oid)
  (awhen (ele::controller-recreate-instance *store-controller* oid)
    (when (typep it class)
      it)))

Thanks for your help, Leslie!
