Hello John
I hope you don't mind if I send you an e-mail directly. I've found
this address on a mailing list.
I am using spring-portlet and it works quite nice. But now I've come
across a problem: I have a small test Portlet which manages a list of
bookmarks. I intended to count the number of times someone clicks a
link and display the list with a descending click count. So to do
this, I added another controller and in the
handleActionRequestInternal method, I increase the click count and do
a response.sendRedirect.
When I call sendRedirect, Pluto complains like this:
java.lang.IllegalStateException: Can't invoke sendRedirect() after
certain methods have been called
at
org.apache.pluto.core.impl.ActionResponseImpl.sendRedirect(ActionResponseImpl.java:142)

So I looked into plutos ActionRespnseImpl. It keeps a flag which is
flipped on certain calls like for example setRenderParameter.
ParameterMappingInterceptor does call that method in preHandle on line
73. So trying to send a redirect will then throw the above exception.
Is it possible to change the spring portlet code so redirecting can
work? Or is this a bug in plutos ActionResponseImpl?
Could you please comment on this issue?
Thank you
Patrick
