v1.6 Beta 2 - possible bug on ajax-enabled multipage forms

Hi

Potentially found a bug using v1.6 Beta 2. Got a simple two page form that has a product using the new radio buttons with the 'other' option enabled on one page and address fields on the other. I'm trying to use the ajax pagination but the next button seems to not work (the page loading icon in chrome appears very briefly but no change on the form).

The same form seem to work fine on the latest stable release (1.5.2.8) with the obvious difference that I can't use the other option. I tried with beta 1 as well though I kept getting error messages on the radio field when I clicked next (which it appears you may have fixed in beta 2?).

When I removed the 'other' field using beta 1 the ajax pagination seemed to work OK so I think maybe this ajax bug may be new to beta 2.

If you need more info let me know

I had this same problem today after upgrading.

I noticed 2 errors in Firebug now that weren't there before:
class is a reserved identifier
jQuery("").chosen is not a function

Here's how I fixed it for now until it's "officially" fixed:
Open the file: form_display.php

The 2 problem lines are 1457 and 585.

For me I was able to comment out 1457 entirely because I'm not using the enhanced UI feature.

And for line 585 - find this:
'div id=\'gforms_confirmation_message\''

Remove the second single quote.
