I guess the problem is that pointer is one-sided from concrete to abstract. With this change, one can go from concrete child function to abstract child (and abstract parent). But it is not easy to find the concrete parent for the consumer as there is no link from abstract to concrete. Thanks, -- Hafiz Abid Qadeer Mentor, a Siemens Business
