@Override
public void willUpdate() {
NSDictionary diffs =
this.changesFromSnapshot(this.editingContext().committedSnapshotForObject(this));
NSLog.out.appendln(" willUpdate() diffs " + diffs);
}
the log shows the attributes that were updated AFTER the saveChanges() is
called.
i am getting tired but I think this is harder than I was originally thinking.
I am on a d2w edit page. I change the values of some attributes and press the
save button. it seems to me I need to do something when I press the edit EO
button. I need to create a copy of the original EO to compare against. so that
when the EO is actually saved, I can read that dictionary of the original EO.
then in my didUpdate() method I could create the email that includes the values
of the original EO and the new updated values.
