[Lift] Ajax Forms and Binding

2009-12-18 Thread Peter Robinett 
Hi all,

I think there is a simple answer to this, but I'm a little confused. I
want to update a bound element when my Ajax form is submitted. Here's
a simple version based upon what I gleaned from the wiki and the
mailing list:

lift:Test.form
  pDisplay: test:display //p
  pInput1: test:input1 //p
  pInput2: test:input2 //p
  ptest:submit //p
/lift:Test.form

class Test {
  var display = 
  var input1 = 
  var input2 = 
  def form(xhtml: NodeSeq): NodeSeq = {
SHtml.ajaxForm(
  bind(test, xhtml,
display - display,
input1 - SHtml.text(input1, input1 = _),
input2 - SHtml.text(input2, input2 = _),
submit - SHtml.submit(Submit, () = {}) // empty method
since our hidden item will be called instead?
  ) ++
  SHtml.hidden(() = {
   display = input1 + input2
   // push an update to display here?
   ()
  })
)
  }
}

Am I on the right track? How do I actually get test:display / to be
updated?

Thanks,
Peter
