Hello,
I have a settings model which initializes from description defaults and
keeps its values as a properties dictionary. If when coding I happen to
change or remove a description, when I edit and save the settings the
stale description still remains in the properties dictionary.
I am looking for a hook with which I can tell the Memento, to clear the
old settings and write the new ones. Is there such a thing?
For example if the model knew it was about to be saved to it could clear
out/reset its values in anticipation.
best regards
Keith
