One challenge here is that the action attribute's value is used to
determine which form bean will be used, including creating it if
necessary. Trying to change it on the fly (which you could do with
JavaScript, for exmaple) would invalidate that choice. It really needs to
be done as the page is being created (but could be a runtime expression).

I suppose you could scan through all the session attributes (this would
work for request scope form beans too), see which one corresponds to a
form bean, and then figure out which action uses that form bean. Of
course, this gets you in trouble if you reuse the same form bean on more
than one form.
