Prefetching: Fetching versus Firing Faults?

Howdy All,

When one uses a fetch specification (either programmatically or from an 
EOModel) you can specify objects to prefetch (along with the fetched 
objects).  For example, if I was fetching a customer object I could 
specify to prefetch the customer.address object and the 
customer.purchases array of objects.

Is it possible to have the same (or similar functionality) when a fault 
is fired?  For example, if I had a salesperson object that had a fault 
for the relationship customer, when the salesperson object accessed the 
customer object it would fetch not only the customer but also prefetch 
(as above).

Would I need to set up my own fault handler (subclass of 
EOFaultHandler) or is there a simpler way?  I would like to be able to 
just traverse the object graph and have this prefetching happen, rather 
than having to do explicit (programmatic or named) fetches all the 
time.

Thanks for any suggestions or pointers.

Cheers,
Ashley.
