Thanks for the suggestions. We needn't bend Wicket to the will of Adobe
just yet...
I've spent most of today cobbling together a wicket form generator that
uses the fillable fields in my PDFs as schematic. It's clunky, but has
helped me to "html-form-ify" the fields on a few of these old forms
already. I'm then using the data I collect within the Wicket html-form
to fill the PDF form. The PDF will remain the final destination for the
data, it just won't be the source. This way, Acrobat needs only to be
used to print the final output. Thus, my consumers get the
pretty-printed forms they want and I get to avoid kludging a way to make
a PDF submit work well. This, not to mention the fact that disparate
Acrobat versions on my consumers' PCs was wreaking havoc on me.
I may already be doing it in the simplest way possible. In the end, I'd
really like to get away from the Acrobat post anyway, so this may all be
moot.

Because PageParameters can't handle that therefor we need a real form
component
where all the multipart handling code is in.
For this we need something like a BookmarkableForm i will try to look
at this after 1.2
So that you can post to a bookmarkable url that creates the page and
then when it is created
it calls the form.submit. This way you could have stateless pages with
forms. Only thing
is that ofcoure the form state is not kept in the session so you can
alter behaviour between request
But this works fine for search boxes, login forms on top of a page or
things like that.

Ok, so it doesn't work. That was a misunderstanding. We are talking
about integrating wicket with other apps. For example Acrobat,
which can
send POST data (no URL parameters) from a form.

Yes, it is. But on the other hand there might be a need to integrate a
legacy app with wicket that requires that a POST request is handled.
Kurt is using a servlet to handle that request, and redirects to a
bookmarkable wicket page. I thought about how Wicket could handle this
directly, without a servlet in between, and PageParameters came
into my
mind.
