This is exactly why I don't want to extend the event type it with the
"scriptable type" method. It isn't adding the fields that is hard, but
creating all the editing and viewing templates.
For what you want to do:
Once you rename the "event_edit_form", then you need to change what
happens when that form is submitted, both on success and failure.
I am looking up where all that stuff is... Those are strangely not
associated with the form itself, but are in
"portal_properties/navigation_properties". You need to look at
"default.event_edit*" properties. I added the ones for my new form to
get things for myself last week, and can't remember exactly which ones
it was. I think it is "default.myevent_edit_form.success" (and failure).
Hope that helps. I am meanwhile going to go the route of creating my
one filesystem product. It may take a while...
