The idea was to "refresh" the FlashScope each time, i.e. get the value
from the previous FlashScope (intended for the current ActionBean) and
put it in the next FlashScope. This does work if I do
return new RedirectResolution(SomeActionBean.class)
However, if I do a forward like
return new ForwardResolution("somePage.jsp")
it gets lost, because if I follow any link on "somePage.jsp" (or submit
a form on that page) the FlashScope is not saved for the next request.
