Marcos,
If you modify the code as I detailed below, your problem should go
away...I've had the exact same issue myself.

When the saveChanges() doesn't fail, you are not ending the undo
group. You should have ec.undoManager().endUndoGrouping() after
ec.saveChanges().

Dear List,
I have never used NSUndoManager at all, I read through the API
documentation and maybe I didn't get the idea, I believed that
beginUndoGrouping and endUndoGrouping were used to mark the
beginning and the end of an undo group. I'm using
beginUndoGrouping and endUndoGrouping as follows:
private EOEditingContext ec = new EOEditingContext();
public void select() {
...
ec.undoManager().beginUndoGrouping();
....
}
public void save() {
try {
ec.saveChanges();
} catch (Exception e) {
ec.undoManager().endUndoGrouping();
ec.undoManager().undoNestedGroup();
}
}
What I see is almost everything in the editing context being undone.
Can somebody please tell me what am I doing wrong?
Thanks in advance!
Cheers
