Try to handle this html form:
<html> <body> <form name="my-form" action="/tbnl/form" method="post"> <input type=text name=":myfield" value="foo"> </form> </body> </html>
after submitting this form in TBNL *debug-mode* you will get:
(post-parameters) (("%3Amyfield" . "foo"))
instead of
(("myfield" . "foo" ))
Any explanation for this ?
