What I need is, to change the Name (PK) value of my object, and here I need to change the Name in every related object. But I need to do this on the same SQL transaction.
The question you'll probably get back from many people is: why are you trying to change the PK of the object? That is supposed to be the one immutable property of the object. If you are changing the PK of existing objects in your database, you may need to rethink your strategy. On the whole, avoid using meaningful data as the primary key and your job will be much simpler. Cayenne gives you a range of options to automatically create nearly sequential primary keys.
