I see the problem -- setting the '_action' attribute after the form is
created doesn't affect form.custom.begin, which is what you are using.
Instead, try this in the view:
{{=form.custom.begin.replace('action=""', 'action="%s"' % URL()}}
URL() should generate the URL of the current action (though it won't include
args and vars, so you'll have to add those explicitly if your URL happens to
use them).
However, I'm not sure it's necessary to have a non-empty action for valid
HTML5 -- see #9
here:
http://www.whatwg.org/specs/web-apps/current-work/multipage/association-of-controls-and-forms.html#form-submission-algorithm.
An empty action appears to be valid.

What do you mean the action field is empty? When I try the exact code above,
I get the following in the resulting source html:
<form action="/testapp/default/index" enctype="multipart/form-data" method="
post">
Are you expecting something else?
