Thanks, Niall,
I think we have reached agreement on what is going on. What this
means is that the MultipartRequestWrapper is not doing a thing in the
present implementation, right? And, what this means is that there is
not available to the present implemenation a
request.getParameter("whatever") method. Right? What is "wrapped" in
the handler are just the values for the files, i.e. name, etc., which
is what you would expect. This means, I think, that we can ignore
MultipartRequestWrapper because it never worked anyway and what
wrapper is implemented can be changed at will. ///;-) Is this too
drastic a conclusion?
I realized that the request handler got the values for the files.
That would have to happen or there would be no way for the upload
application to work at all. Right?
Mostly, I would like to be able to interface in various ways between
the populator, whatever that turns out to be, and the ActionForm. Am
I being obtuse about that?
What I would like to see is the default upload application deferring
so far as is possible architectural decision until the application
itself is implicated. I would like to see the framework avoiding
being a "servant" to the application. This is not necessary, I think,
and undesireable. Do you agree on that?
Thanks.
Jack
