I tested this in version 1.4 and Version 1.5.rc3.4
I have a form with conditional logic on 2 dropdown fields.
The form is in a text widget as a shortcode and appears in a modal window.
Firebug's log limit has been reached. 0 entries not shown. Preferences gf_apply_rules is not defined [Break On This Error] </div><script type='te...11: }, 'animation' : 0};</script>
if I remove the logic, the error disappears, but the submit doesn't work??
if I use a simple form, it works fine.
I really need to get this working as it is a requirement on a client project

I can also provide the form XML export
