An example of a stochastic differential equation is given with uniqueness property, that is, for each initial value there is a unique solution living on some probability space. This equation has another solution living on a different probability space and does not have strong solutions. This illustrates the fact that pathwise uniqueness is really needed for existence of strong solutions.
