We have an install of GV where the client has created a rather large form, about 400 fields with roughly 95% of them drop downs. Each drop down has 10 - 15 options, and they is also conditional logic with most of the fields that allow other fields to display based on sections.
We are seeing issues now when the client is adding new additional fields. Looking at the network view in Chrome Dev Tools we are seeing that the /wp-admin/admin-ajax.php if returning EndUpdateForm(1); so this appears to be working.
Additionally, we have seen it return a simply -1 of which we assume is an error.
You can see the JSON that is being created here, http://www.adirondackdreamhomes.net/json.txt
Is there a finite about of data that can be passed? Are we attempting to do something that is just to complicated for the GV system? Any help or direction would be appreciated.
