Your not thinking very hard about it obviously.
Have a think about this scenario then (which is a common problem I and others have had to deal with before):
User is presented with a table of records containing links to edit individual records. Clicking on the link opens the form for that record in a new window (or maybe it doesnt and the user chooses 'open in new window' themself from the context menu). This is because the user often needs to be working on lots of such records at the same time.
Now let us assume that the ActionForm for the record editing form needs to go in session scope (nb: in request scope there is not a problem so if the design can be done practically with request scope that is much better).
During the course of working with these records the browser is going to be making several trips back to the server to refresh that record. (Maybe it has several select boxes depending on each others value, or it pretends to do tabpanes or is some kind of wizard or whatever).
Remember now that the user has several different such records open in different windows. Different record instances but same type of record - and record form - and record action (we are talking about the same ActionMapping here obviously).
Have a think about whats going to be happening with that session scoped action form...

That is correct, but these situations do not, so far as I can see, cause problems.
