Populate form controls acting strange in 8.1.1.11

Hi,

We have a solution that used a custom OpenUI Model and Renderer to populate a form control from custom params.

It worked fine in 8.1.1.10, but when we upgraded to 8.1.1.11 it no longer works. The page loads properly, but the default values are not present, and if you change a form control (pick a LOV), the values appear as expected. When we put in break points, the values appear and disappear several times.

I attached our renderer. I've removed irrelevant items. The model isn't doing much other than form validations.

It's a bit of a shot in the dark. I hope someone has had a similar experience.
