How to get the old values when overriding preUpdate?

[Jazzgeir]

I need to store all changes (overwritten values) in my tables (80+) to an external database in a specific format. I have overridden the preUpdate function of all my objects, but when i try to get the old values for safekeeping in the external database, I only get the new values. If my preUpdate call returns false, Propel revoke the changes of course, and roll back to the old values. But how can I get hold of these? I have tried both the standard getters and the getByName function. Both returns the new values... And getting the same object by way of create()->findPk() also give me the new values. Due to caching possibly.

I would think that the intuitive way of accessing the old values would be getting the old values prior to returning true in the preUpdate hook, or having a special function for accessing the old values available in preUpdate. I would think being able to read both old AND new values would make perfect sense in the preUpdate hook, actually?

Has anyone got any thoughts or ideas about this?
