Re: Undo/redo implementation & JMI compliance

Hi Svata,
actually getByMofId operations can be very easily implemented in MDR. It 
is just one line of code. I know we have been playing with the idea of 
adding it somewhere for quite some time.
We just didn't agree in where to put it in the API. I guess that 
MDRepository is the right place.
