Mauro,
I was reading somewhere (not very sure) that sendRedirect() should be used for
exception situations
only and not normal processing as the call to this method will clear all your
request object
data before the called resource gets control.
I guess all changes to the session object will also be lost.

Subject: Re: sendRedirect problem, loosing bean changes!?
Paul,
actually I don't re-reference it. I use it as it comes from the
<jsp:usebean ../> tag.
What I am wondering is how the sendRedirect works. Does it throws an
exception? that 'could' explain why I loose all the changes I do to my bean.
Otherwise what happens?
