> I'd like to subclass DirectService by slightly modifying the behaviour of the 
> service() method but leaving the getLink() method untouched. I have the 
> following problems with this:
> - DirectService.STATEFUL_ON and DirectService.STATEFUL_OFF are private, so I 
> cannot copy-paste the code from the original service() method to my subclass
> - Of course it would be much better to prevent copy-paste. For example the 
> service() method should be cut into at least two separate methods: extracting 
> parameters and executing service related tasks. This is necessary to execute 
> the service without a RequestContext (for testing or internal invocation).
> - the above subclassing problem is true for all services
> All the above is irrelevant if default Tapestry services are not intended to be 
> (easily) subclassed (but I think they should be).
> Thanks,
> Norbi
