Thanks Cyryl,

Well I was hoping not to have to deal with "I have to store the object somewhere before even knowing I might need it's previous state later";)

Hi,
I'm not sure my subject is understandable, anyway.
Assuming I have an object "x", I'm manipulating it in an editing context. At a certain point I need to get the original object (the one from the database) but without changing anything to the one in my editing context.
How could I do that?
I need the object in its globality, so if I can get the object directly and not a dictionary of its values it's better:)
You can answer "bla bla project wonder":) but please point me to the correct method as I didn't find it for now;)

one of the possible ways of doing that is to make object.snapshot() before changing it and after some time create new editing context , fetch the object into it and then do objectInTheNewEditingContext.updateFromSnapshot()


changes would be made to the objectInTheNewEditingContext only
