i have this on my todo list, a convenient solution will still take some time. As always, a quick solution is easy, a full blown one is more complex. Quick solution: to fire an action in certain situations, subclass Form and FormPage and overload methods called in the interesting situations (e.g. the method save_data). This allows to call application specific calls before or after the methods in question.
if you want to go that way, just send me mail, i'll help to decouple Form and FormPage to make subclassing easier. I am quite busy until i leave for guatemala to get everything finished.
