The whole demo program works fine: the form appears. If I add an "action=..." in "FORM(INPUT(_type="submit"), *checkboxes,_name='myform')" another page is called (as expected).
The problem is that there is no value in request.vars. I don't know whether it is possible to add a form, which can be recognized by "form.accepts". Something must be wrong, but I think, it is not ajax-call.. 2011/8/23 Anthony <abasta...@gmail.com> > I don't think you are using jQuery.ajax correctly.
