Currently, when you submit data through a Woven Form that
raises a FormError for one reason or another, another form
is generated for you in a plain white page.

It is preferable to have the error reported in-line with the
_original_ page that displayed the form. This is tricky, but
there are ways to do it. Here's one (so far sketchy) idea.

I propose a "FormPage" class that allows the programmer to
specify one or more Forms that will be used in a Page. All
of these forms, in the template, should have an "action"
that references the same FormPage. The MethodSignatures for
these forms will be associated with a callback (as usual)
and a Redirect (as idiomatically usual) that points to,
e.g., a results display page.

So, our FormPage is also the processor of all forms used in
that FormPage. If a FormError occurs any time during
processing, then the FormPage can rerender itself entirely,
putting an error message near the appropriate form that the
user put bad data into.

Thoughts?

We need a FormPage thing, that's for sure, but the one you
suggest is impossible.  a URL for GET may specify multiple
forms to display, but a URL for POST must only specify one
form to submit.

The FormPage we need is a Resource that has *2* URLs for *1*
form.  That way you can bounce back and forth between
displaying errors on the "display" template without creating
confusion on the "post" URL

take a look in sandbox/glyph/formdemo for an implementation

Looks like dp is on to this.

This bug is being resolved, wontfix, as woven is "almost deprecated" and unmaintained. Use nevow 
instead. See <http://divmod.org/users/dp.twistd/wiki/> and the twisted-web mailing list <http://
twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-web>.
