In early versions of Struts, form beans could only be stored in session
scope, so the Actions were programmed to remove those beans as soon as
they were no longer needed. Once the support for using request scope was
added, the example app was changed so that it will work correctly for
*either* scope (request or session) for form beans.
You are correct that the removeAttribute call is not required for request
scope, but it doesn't hurt anything either -- and it is part of
maintaining the compatibility so that this code will still work for
session scope form beans.
