Just for the record --- this would tracking changes to a document (tracking
changes to a form would be an issue for designers to keep track of the design
changes - interesting as well).
I have sort of been looking for stuff like this since I always had my generic
"history of changes" function (stores the changes made to any of the fields on
a document in a history-field) which works nicely on the Notes client
(querySave), but I had problems getting this to work from the web.
Using the mentioned event will finally make this possible from the web as well.
