Bug?! remote_form_for does not provide ajax

Hi guys,

I've downloaded the liveValidation JavaScript from
www.livevalidation.com.

I found that the remote_form_for does not work with the js. The
necessary AJAX code in the "onsubmit" part of the <form> tag is missing
**Sometimes**

yes, it's sometimes:

1.a save button onclick="submit button.click" - ajax ok mostly
1.b save button onclick="submit button.click" - ajax failed sometimes
unless I using prototype to observe some other control (e.g.
$('othercontrol').observer('click', test))
2. save button onclick="form.submit" - ajax work but nothing can be Get.

All in all, the remote_form_for is probably affected by the validation's
JS event.

Is it a known bug or what cannot be done together with the
remote_form_for?

Thanks much
Arthur
