[jQuery] bind validation to an ajax included form

[[EMAIL PROTECTED]]

HI,

I include a form with an ajax call:

<form id="exportRb" class="cmxform"  method="post">
<label for="expMailAddr">E-mail</label><input class="text" type="text"
name="expMailAddr" value="" />
<input type="submit" class="submit" value="Export"/>
</form>

The form is displayed in a thickbox.

Now I tried to ue the validation plugin(loaded in the calling page)
adding to form tag:

onubmit="setValidation(this)"

and with this script inline:

function setValidation(this){
  $this = this;
  $(this).validate();
});

I think to be copletely on a wrong direction.
Some suggestion.

Andrea
