error on live system not present on local dev

Hi, I have a webmaker app that I designed that was working perfectly until a recent re-publish and now whenever I try to change data on a repeating record set of fields and submit to the server, none of the data gets saved.

The odd thing is, with the exact same data set (I did an export from live and imported it to my local dev mysql instance) on the local dev instance of webmaker, it works perfectly with the very same version of the app that is deployed to the live system.

I checked out the differences between the XML document that gets sent to the controller on my dev system versus what gets sent on the live system (I enabled debug logging and loaded up the log in the test dashboard on my local dev box). On the one that is working all the data gets bound correctly to repeating <record>...</record> elements with all the record data inside the <record>...</record> tag as separate tags, as expected. However on the live version the data is not like that, nothing is under the <mvc:unbound> tag, and I get a bunch of records that look like this:


<mvc:eForm xmlns="http://www.hyfinity.com/xplatform" xmlns:mvc="http://www.hyfinity.com/mvc" xmlns:xg="http://www.hyfinity.com/xgate"> <mvc:Control> <record_repeat56want_shirt xmlns="http://www.hyfinity.com/mvc">0</record_repeat56want_shirt> <record_repeat29zip xmlns="http://www.hyfinity.com/mvc"/> <record_repeat95last_name xmlns="http://www.hyfinity.com/mvc">redacted</record_repeat95last_name> <record_repeat57first_name xmlns="http://www.hyfinity.com/mvc">redacted</record_repeat57first_name> <record_repeat89trusted xmlns="http://www.hyfinity.com/mvc">0</record_repeat89trusted> <record_repeat28emergency_contact xmlns="http://www.hyfinity.com/mvc">redacted</record_repeat28emergency_contact> <record_repeat49attendee_comments xmlns="http://www.hyfinity.com/mvc"/> <record_repeat88zip xmlns="http://www.hyfinity.com/mvc">redacted</record_repeat88zip> <record_repeat52middle_name xmlns="http://www.hyfinity.com/mvc">redacted</record_repeat52middle_name>



with the working local dev system, the document that is displayed as the incoming document on the test dashboard looks like this:

Why the differences? How do I fix this?

This is rather important that I get this fixed asap because this system is to be used live tomorrow.

BTW the live server architecture is ubuntu linux running nginx reverse proxied to tomcat which is running the webmaker app. With this same architecture the app was working perfectly in the past.

My browser that I am experiencing this in is chrome 21.0.1180.60 m

BTW with the number of rows on the repating record set for editing, the resulting document that gets shown in the test dashboard is about 180kB. I have ensured the tomcat and nginx configuration is set to allow a payload of a much larger size than this.
