Hi all,
Here's a question: has anyone ever tried implementing undo / redo
support for EOF, that is not based on the NSUndoManager? Or, can one
estimate if it is even possible, I am just trying to think about the
possibilities and pitfalls... Here are a few specific questions:
1. Inserting records, then un-inserting and re-inserting them...
Could the same EOs be used? Would the ec flip? Would the object graph
roll back to the same state, regardless of the deletion rules of
relationships of the inserted object?
2. Same questions about deleting records.
3. Could relationship editing be undone and redone by simply applying
reverse actions? Would EOF accept that without problems?
Would it be better to simply ignore insertion and deletion, and focus
only on the editing? Anything else that might be a problem that I've
missed?
Thanks for any thoughts,
Flor
