Hi,
Thanks for your response. Yes, I think the interceptor will do. However, it
just feels a bit clumsy to write 6 lines of XML in order to get
functionality that Struts 1 provided in one. It may be a great solution for
cases where your action messages have to survive multiple redirects but in
99.99% of my cases it is just one...and I am using quite a few of those in
my apps. Thus, I miss the Struts 1 solution :-)
Regards,
Gunnar
